During vaginal sex the penis goes into the vagina. Foreplay is important. It gets you both sexually aroused and ready for penetrative sex. It makes vaginal sex more enjoyable for both partners. Having vaginal sex without using a condom puts you and your partner at risk of unplanned pregnancy, contracting HIV and other sexually transmitted infections STIs. Put a condom on an erect penis before it touches or enters the vagina.
The following situations and conditions can contribute to or cause pain during intercourse or other forms of penetration. Sexual Intercourse or Penetration for the First Time The first few times you have intercourse or experience vaginal penetration, you may feel a small to moderate amount of pain at the entrance to the vagina. There can be some bleeding or no bleeding at all—both are normal. The reasons for the pain are not always clear, but it is typically temporary. But not all hymens meet these criteria, and women without substantial hymens can also experience painful penetration. The truth is that research has not told us with any particular specificity why it is that this discomfort happens, or why it happens for some women regardless of hymen type and not others.
