How deep should the penis go during intercourse?

How deep can and should the penis penetrate the vagina?

What will the penis hit?

Will sex hurt?

Is it dangerous?

What will the penis hit?

These are common concerns of women as they begin to experience penetrative sex (intercourse); these questions and worries are there because the vagina is an invisible canal. The woman cannot observe what is ‘there’ nor what happens when the penis slides in and thrusts.

  1. For vaginal depth, read our other post, Vagina – endless?
  2. Should you need to guide his penis in?  Read Guiding the penis?
  3. The uterus sits at the end of the vagina, and its bottom opening – the cervix – is the part that the penis will tap during thrusting, an alignment that is natural and designed to function just so.  Please read our other post, Hitting the cervix.
  4. How deep will he go? As deep as your vagina allows; as deep as is comfortable for the (receiving) woman; as deep as your and his physiques allow; as deep as the passion asks for…  Men can adjust their penetration depth, so ladies, you must speak up your preferences so the sexual event will be free of stress or pain.

    My husband’s penis is too small it is just 5cm
    He can’t go so deep in intercourse
    Can I be pregnant with that small penis??

      Yes, you can. But, if you are having problems, check with your OBGYN.

      Of course you can get pregnant with a small dick, but if you have to ask that question, I don’t think you should have baby.

    I’m 13 years old and I was recently dumped because I wouldn’t have sex with him because I was scared it would hurt will it hurt the further he goes

      Please listen when I say, do NOT go after someone that doesn’t have respect for you. When you are ready to have sex, it’s on your time no one else’s. My ex boyfriend left me 3 years ago and I am convinced that it’s because I wouldn’t sleep with him. He would cheat on me to have sex and I’m assuming it’s because I never gave it up. I was at my lowest point in life that I begged him not to leave. Girl, love is so powerful but trust me the right one is out there. Do not settle for someone who doesn’t meet your expectations.

      You should not be pressured into sexual intercourse no matter age or situation. Your boyfriend will have been as confused as you as his friends will be talking about doing it and he will have pressures around him too but he should not press it upon you. You will be around 14/15 now but to anyone else that may be reading this, dont put in to pressure, do not feel that you owe it due to being in a relationship. Sex is a natural process and you will know when you actually want it if your partner truly loves you they will wait, sex is a passionate connection which creates a bond between two people. If you are engaging in consensual foreplay with your partner but are not wanting sex let them know as they may wrongly be stuck in the moment making you feel pressured.
      If you do decide to engage in sexual activity please be safe use protection and do it somewhere you feel safe if that is at your home or there home if you feel safe.
      Have fun, be safe and stand your ground

    Can deep penetration cause trauma to the bladder

      Not usually as you are built for penetration as deep as your vagina is capable of. But, see your OBGYN if in doubt about your particular situation.

    Can the penis cause irritation after having a c-section

    • Ditza Katz January 29, 2019 at 8:07 pm / Reply

      The uterus/cervix may still be tender after giving birth even you are allowed to resume vaginal intercourse. But since we do not know you/your vagina, you may want to consult with your doctor.

    So I just bought my wife 7inch /2-1/4 inch thick . So I’ve noticed that when I penetrate it deep she tends to get more wet and tends to want me to keep going deep in her Vagina. So my question is ? Do you think she is liking the deep penetration of her vagina , she likes me to go as deep as I can , and keep it there with up and down movements in her Vagina. She wants to try an 8 inch dildo , could she be liking this way of foreplay-sexual intercourse?

      It is typical to have some of the ‘fluids’ come out of the vagina after he ejaculates. Check with your doctor about your fertility.

    My husband and i have been having sex ever since we got together 6 years ago. In the last year sex has been so painful hust as he is entering me. So painful that i cant carry on. Im wet enough. Just dont understand how everything can be good then it becomes painful.

      There are always reasons why intercourse turns painful, and you/your doctor need to explore it.

    Can you have sex with out putting your penis in a vagina ? Should you wear underwear while you have sex with your partner?

    • Ditza Katz October 22, 2018 at 5:44 pm / Reply

      Sex includes many types of activities, penetrative being only one of them. If you do not wish to get pregnant, take necessary precautions (thick underwear may be an option).

    • Ditza Katz September 12, 2018 at 5:07 pm / Reply

      You need to limit the depth of your penetration. You can do that by using different sexual positions, and by minding how deep you go in/thrust, or by using a penile ring (available online) that will physically limit your penetration depth.

    Hello, we’ve been trying to have a baby for a year. Report seems to be normal… Doctor presumes position and not having deep penetration could be the cause…we both are200 percent satisfied but still no result… While ejaculate I see most of my semen comes out….I’m not sure what should I do….

    • Ditza Katz September 12, 2018 at 5:10 pm / Reply

      Not going all the way in is one possible answer although women often get pregnant without full/any penetration. And if you see the semen when you ejaculate, then you definitely are not going into her. Try different positions and assess.

    Actually i did sex with my gf and i just inserted the head of my penis into her vagina

      Yes, there is. Make sure she sees her doctor for options.

    can women be sexually satisfied if her husband is 100% loving , supportive, caring , expert in foreplay but he is impotent. i am elderly man good in all fields which are important for women except that i cannot penetrate her.

    • Ditza Katz August 20, 2018 at 6:29 pm / Reply

      Absolutely, as long as she is okay with not having vaginal intercourse, a common situation that most women are okay with. Keep the communication open, and explore all other sexual ways that you and her can enjoy.

  • Ditza Katz August 6, 2018 at 2:07 pm / Reply

    Virginity is defined as having had a penis in vagina. If you had vaginal intercourse at least once, you are no longer a virgin.

      Yes, you can get pregnant with partial penis penetration. As to the pain situation, we cannot tell without examining you.

    I’ve only had sex 4 times ever in my life and it’s with the same person. When I have sex and he pushes in deep it hurts. I presume the cervix tapping. After sex though it seems as tho my ovaries? Are hurting and it feels like I’m on my period. Also I read on line that I need to be readied up before having sex but he just pushed it straight in is that a problem could that cause damage internally? I just want to know because I’m new to this whole thing and when I read online I just gather more and more questions without acctually getting an answer

    • Ditza Katz April 25, 2018 at 6:46 pm / Reply

      Yes, it is possible that hard tapping against the cervix during penile thrusting may result in your symptoms. Ask him to ease on it and see if that helps, as well as try intercourse in different positions, which may also help.

      As to ‘ready yourself’ before penetration: not sure where you saw it online but that is not a typical requirement, unless you are referring to adding lubrication or if there are medical issues involved.

  • Ditza Katz February 2, 2018 at 4:43 pm / Reply

    That is all in the definition: some would argue that the penis has to be fully inside while others may say ‘less than fully in’ is also accepted. But you definitely need to get in deeper than 2cm in order to pass the vaginal opening/hymen.

      Can a 4.5 inch long penis be satisfying if a wife has a longer vaginal canal like 6-7 inches long? Because I don’t fell much friction some but not to much. And I never been abe to fill her canal up. I know I’m on the small side. I some times fell cheated by mother nature and makes me feel sad that I don’t measure up. Please help !!!

      • Ditza Katz May 31, 2018 at 11:20 pm / Reply

        Only your wife can answer the question (whether she is satisfied). A constructive dialogue between you is key.

        On a general note, women’s satisfaction is composed of physical and emotional components so you have plenty opportunity to make her happy.

    Is 17 cm length and 13 cm circumference alright for a girl pleasure wise

    • Ditza Katz December 10, 2017 at 2:34 pm / Reply

      The length of the penis does not matter much because it can only go in as deep as the vagina allows. As to girth, 13cm circumference is average and should fit the vagina. Lastly, women can have penis penetration with and without any pleasure! The vagina is a passageway for more than just a penis, i.e. finger, gyno exam, tampons, childbirth, and pleasure is a choice, not a must, for penetration.

  • Ditza Katz November 28, 2017 at 3:52 pm / Reply

    • Ditza Katz November 27, 2017 at 4:13 pm / Reply

      Although we cannot tell for sure without examining you, we can say that depth may affect a woman as you described. Try putting a pillow under your buttocks and/or having intercourse in different positions (= different depth of penetration) and see if that help.

    can a 5 inch penis be satisfying to women?

    • Ditza Katz November 27, 2017 at 4:10 pm / Reply

      Women’s satisfaction is not just about penis size, but also about her emotional satisfaction with the partner, the relationship, and sexual choices. We recommend you have an honest conversation with your female partner during which you will ask us this very question.

    • Waqas Ahmed June 15, 2018 at 9:21 pm / Reply

      No A 5 inch penis is never satisfying to your partner.
      I know this to be true because I have a 5 inch myself and I slept with all race of woman.
      And they never wanted me because I was not at least 7 inches like their ex’s…

  • Shane Colunga October 5, 2017 at 2:45 pm / Reply

    When your wife preferred your manhood is 3 inches shorter and complains the head is tooo big, is hers small or is mine truly too big, tried the pillow in the small of the back, complaints originate during missionary position.

            Please I want to know why legally married women engage in other affairs outside marriage. Is it proper for a woman is married with two lovely children to still communicate with her ex. Is it okay for her to get too familiar with another man so much that they communicate on phone on a daily basis and claimed there there was nothing btw them when asked. Please I need your honest reply. Thank you and God bless you immensely.

          • Ditza Katz November 24, 2018 at 9:34 pm /

            You may want to speak with your doctor or with a psychotherapist about these concerns.
