I have been experience severe itching all throughout my crotch area for about a year now and over the last couple of months it has gotten worse. There's is no visible signs of abnormal skin except for one bump that appeared a few days ago right above the penis and scrotum. It looks like a pimple but it hurts a little bit. I have never had sex but frequently have unprotected oral sex with my girlfriend (I'm the only guy she's ever done anything with, even kissing). I went to a doctor who prescribed me some sort of antibacterial cream and Z pack pills but it doesn't seem to be helping. The itching seems to get severely irritated right after receiving oral sex and especially while I'm working and wearing jeans, but I don't sweat during my job. Please help, anything helps me out!
