I have gotten an irritation while at work around my crack of my ass. When I came home, I figured it was just from shaving around the area. However, a few hours later, it seemed to have spread up my ass to where I can visably see it. They are small, clustered together, and I feel a slight pain, though more of an irritation from them. I have not had sex in three weeks, and I don t ever do anal. I don t know what they could be.
