I had sex with a girl a couple of weeks ago , the first few days I was alright but than I saw a pimple that's hurting when touched or pressed on the right side of my ball sack just underneath the penis . I thought it will be ok on its own but than that area became sticky I don't know if it's from the pimple or that area got bruised while having sex. And such a place underneath the penis will always stay moist so less chance of drying the wound out. I used provate cream for irritation . But today I see small red dots like pimples like the tip of a pen spread around the area . The skin there hurts they pustules or what I think yes. I want to know what is this illness , is it something serious and what is the cure of this.
