It’s highly unlikely you have pgad - this is a disorder that affects only women. It’s unlikely to happen to men because after several orgasms there’s generally no more response & most likely you’d just feel soreness or swelling. Irritation from a UTI can sometimes feel a little bit like sexual arousal. Not sure why the antibiotics didn’t clear this up for you, but you should see the Dr again, tell him/her you still have this, may have to run more tests or try a different treatment. It can be dangerous to try & self-diagnose via Internet, we tend to think everything sounds like our own symptoms...
