So tonight i had rough sex with my boyfriend, and it hurt during which is unusual. i looked down there after the fact and couldnt see anything so i took a photo and i found something that terrified me. A big bump next to my vaginal entrance! i included photos i took of it, can anyone offer any advice? the photos were taken right after the painful intercourse so i am a little red and swollen if that plays a role. i circled the area where the bump is. 
looks like it could be a cyst. be worth getting checked out by the doctor in any case
maybe its a ingrown hair. is it normal for you to be that swollen? i have never seen that before.
she’d just finished having rough sex, so i figured it was likely that?
