I had sex with a girl I didn't know 6 weeks ago. I have been tested at 2 clinics for all std's an were negative. I have had an a slight burning sensation( not on the penis but just under my waist line). I cant find any rash.blisters, bumps, redness or anything, but It feels different. I have read all the info on all the sites about herpes and it does say you will feel the burning,tingling,iching in the spot prior to a breakout. It also says you will break out on your penis, scrodum anal ( not of thses have this feeling) but nothing mentions below the waist I have had the feeling for over 10 days with no breakout. Is this herpes or what is it? please help
