i have like 3 little, and i mean little blisters on my shaft, im freaking out that its herpes, but from what i have read online i have no symptoms expect for blisters. my roomate said herpes are usually bigger than what i have. and they dont itch, scab, hurt or anything else that the herpes site said. can it be from masturbating? and if so why now and not before. i just had sex about a week ago with my ex and pulled on it a little maybe twice since. anyone have anything to comment please do
