hi i had sexual intercourse with my boyfriend last weekend and 2 days later i noticed theses bumps between my vaginal and anal region. I ts not the first time i have noticed these bumps after having sex with him. the bumps are tiny and clustered and are very red on the tip. I am currently on birth control so we normally have unprotected sex. Is it possible that i may have contracted a std? p.s. we have never had anal intercourse.
