I think I might have an STD. I had unprotected sex the other night and I just noticed a scab on the tip of my penis. The tip also appears to have these hard to see little white spots under the skin, kind of like a transparent appearance. It doesn't hurt or anything. Anyone have any advice as to what this may be?

I'm not sure what it is but you could tryout this website (http://symptoms.webmd.com/default.htm), if u don't find out got to the doctor really soon, and next time don't be a fool protect your tool

Well you deff got and STD! all I can say is go to the doctor and see if it can be treated and what kind it is. Next time wear a condom.
