As soon as I get hard, both side of my lower abs around my appendix but on both side rather than just on the side of the appendix, get swollen. It feels like two balloons are inflating. I am wondering if anyone else experiences that and what theirs feels like. I am thinking its gas or my prostate swells up only when I am hard. I dont get it. Also when Im hard I tend to clench my anus. Does anyone else notice that?
