if you noticed a change, it may be something. If you're just paranoid and have become hyper-aware of the sebacious glands every male has in his skin, well, then don't lose any sleep over it. The only way to know for sure is to go get checked by a doctor. I suggest Planned Parenthood, they are VERY discreet.

I also suggest you read thru some of the posts on this site, post by people who think they have HSV2 (which 1 out of 4 people have and never goes away) or HPV, or chlamydia or gonnorhea or syphillis or a whole host of other weird *** diseases and ask yourself is it really worth it not to wear a condom? I know, condoms suck, right? Actually, check out the condom Durex makes called Avanti... it's not bad.
