Does it hurt the first time you have sex?
If you experience pain during penetrative sex, it could be for a variety of reasons. If your hymen is still intact, you may experience pain and a bit of bleeding as it stretches during intercourse.
The hymen is a thin, ring-like membrane that may either partially or fully surround the entrance of the vagina. It has an opening that varies in size and can be thick or thin. The more stretchy your hymen is, the less painful first-time sex is likely to be. If your hymen is not as stretchy, first-time sex may hurt and/or bleed a little. This is the most common source of first-time sex pain.
If you’re concerned that your partner’s penis may be too large and that this will hurt, try not to worry. Although this is possible, it’s very rare. The average penis size is about five to seven inches long when erect, and the vagina is typically between three and seven inches long. The vagina can stretch high and wide during sex and childbirth, so a too-large penis is usually not a cause of pain.
One common cause of pain or discomfort is when the penis is deep in the vagina and makes contact with the cervix. This may feel more uncomfortable than painful, and you can usually resolve it by trying a different sex position.
