I am a 26 yr old female worried about what i have on my buttocks. For a few months now, I've had what looks to be a breakout of acne on my butt on one cheek. I have picked at it... not sure if thats why it is still there... I've also been using a body acne wash that seems to make it fade when i leave it alone. Yesterday however, I noticed some new smaller and a bit different looking pimple like things on my other butt cheek. Like i said, they're a bit different looking, like kind of the small bumps one has on the bak of their arms... I did have sex unprotected with someone a few months ago, a few times, after i had already seen the stuff on my butt. I never actually looked at his penis and such, so I dont know if he was ok. I really regret that whole thing and feel so stupid! But I am freaked out as to if this is an std or what! I dont have anything else going on down there that seems to be of concern. But the fact that i now have things goin on on both sides of my butt cheeks, is bothering me. The ones that I've had only hurt when i have messed with them. I started to mess with the new ones so they hurt only a bit now. I have a total of 5 or 6 that I've had for the past few months and the news ones maybe about the same number. I guess i slightly itch. None are pussing tho, which i read is what happens with herpes. So i wonder is it herpes, some other std, or something else. I'm really worried because its very scary to think about having an std like this.. please help with your advice.
