Okay so I recent had sex in the butt or whatever you want to call it. Got a sinus infection- so they gave me antibotics. I then got a yeast infection with the antibiotics and it has been very intchy down there. It has been very red, I think my yeast infection is going away but my crack in my butt is really itchy, my tate is really itchy and there are little bumps around my anus whole. I am not sure if this is some kind of bacterial infection, or if this is irratation of doing it in the butt. It was a little more rougher than usual, so I am not sure what's going on. Please Help!
