I can't have sex with my boyfriend. I'm 16 and we tried to do it but it didn't go in and it hurt and I was bleeding a little. What should I do? Why is this happening? Am I too tight or is his penis too big?
Okay. What kind of medical issues could cause this?
Some medical conditions that can cause difficulty with intercourse include vaginismus, vulvodynia, and endometriosis. But again, it's important to see a doctor to figure out the underlying cause.
