Question: I had sex over the weekend. I was very intoxicated, but I was very clear that I wanted to participate. I woke up to see blood on the sheets and at the time I couldn’t figure out where the blood came from. I was not in pain nor was I expecting my period. The last time I had intercourse before this was about a month. I have gone longer without sex before and did not bleed. This is not my first time having sex, nor is it my first partner. What could have happened? Is it possible that I finally had my hymen break? Or is it possible that he penetrated too deeply? Is it an allergic reaction to the condom or the lube? I am very embarrassed by this and very confused.
Many Possible Reasons
There are many possible reasons for bleeding during sex or bleeding that occurs after intercourse.
Since you have previously had intercourse before, it is unlikely that you “broke” your hymen (the hymen is a thin layer of tissue that partially covers the vaginal entrance and is filled with blood vessels, thus causing bleeding in some women when it first tears due to penetration).
The hymen may tear from various types of penetration including intercourse, vaginal fingering, or insertion of a sex toy. The hymen does not “grow back” if you have not had sex in a long time, as is sometimes mistakenly believed.
Vaginal or Vulvar Tearing
It is possible that you experienced some vaginal or vulvar (outside parts of the genitals) tearing during intercourse. If it was a small amount of blood, it is unlikely that you would have experienced much pain.
If there was a large amount of blood on the sheets, then one would usually expect some pain or discomfort, though perhaps the alcohol dulled the pain at the time and the pain was resolved the next morning. We know that alcohol lowers inhibition, and it may actually work against your physical arousal, making intercourse more difficult and contributing to the risk of tearing.
When women have tearing around the entrance of the vagina, or just inside, healthcare providers sometimes prescribe specific antibiotic ointments in order to reduce the risk of developing an infection. Therefore if you think you may have tearing inside, you might check in with your healthcare provider so that he or she can examine you (small vaginal tears, by the way, happen to many women at one time or another; larger tears are less common and should be examined by a healthcare provider).
Why Might Tearing Occur?
Why might tearing occur? It often occurs during rough penetration or when a woman is not well lubricated ( e.g., if you did not spend much time in foreplay before having sex or if sex went on for a long time, both of which can occur while intoxicated as couples sometimes jump into sex and a man’s orgasm may be delayed or not occur at all, thus leading to sex take longer than usual).
Though women can react from a hypersensitivity or allergy to condoms or lubricant, these are unlikely to cause such bleeding. Another possibility is that one of you may have had a cut elsewhere (i.e., on your knee or hand). That happens sometimes too, with couples mistaking blood on the sheets for vaginal bleeding.
A Fairly Common Occurrence
Whatever the cause, this is actually a fairly common occurrence and nothing to be embarrassed about (though we understand that it can feel embarrassing at the time). It sounds like you have learned a bit more about how you feel about sex, drinking, and mixing the two, as well as communicating with a sexual partner.
It is common for men and women to find it difficult to discuss sexuality (particularly when they are relatively new to sex), and it can feel even more challenging to discuss sexual topics if you don’t know each other very well.
Because vaginal bleeding during sex happens to most women at some point, many couples take it in stride and move on. If you feel like you want to discuss it, you might start by letting your partner know that it feels awkward for you to talk about it, but that you’d feel better if you could.
