So this isn't a picture, however no one else has been able to tell me what's going on so I figured why not consult you ladies. For the last month or two I've noticed a mild pain I get after masturbating. As of right now it always goes away on it's own and has never taken more than an hour to fade. The pain is typically in my lower abdomen and sometimes around my anus. I was just wondering if anyone could tell me why this is happening and if I should be concerned.

Note: I'm not sure if this would happen during sex as well considering I'm a virgin. That also rules out STDs.
