for the past week my penis and balls have been SUPER itchy, the underside of my shaft is all red and very irritated. i have never had sex so STDs are out of the question. but 2 weeks ago, i was in a play, and before we go on, its tradition to rub foot powder on our balls. could that be why its all itchy? that was two weeks ago though, and it just started itches this week. whats going on!?
