Hi, I recently (as of 2 days ago) developed these small, reddish bumps only on my scrotum. At first I thought they were hair follicles, but there s no hair on them. They don t hurt, but do get a little irritated when they come in contact with anything (my boxer briefs usually). I m 17 years old and have been sexually active but all protected and with one partner. Any idea what it could be, should i be worried, and how can I treat it?
