Don't know if i'm in the right place, but i just noticed my penis was sore... I flopped the sucker out and found a HUGE pimple on it. Like, a BIG one, and it was filled with puss and prevented me from masturbating. I'm quite worried... It couldn't be a STD because i'm a virgin... anyone know what it could be? (i'm 15 and masturbate like every day )
