I am circumcised, usually the area where the foreskin would attach is rugose. I just noticed last night that there was a small hard area on the topleft side that when I squeezed it, white discharge came out. It reminded me of a pimple almost, it just wasn't expanded above the surface. I applied betadine to the area. I looked up genital warts and herpes and it doesn't look like any of the pictures there. I don't seem to have any other symptoms. Though as a kid, I would get canker sores from time to time (and my mom had mono before I was born). I had mono a few months before, anyway, lately I am really stressed with final exams and work (I work alot). I have a girlfriend, and I am concerned, that's why I am asking. She never had sex (of any kind) with anyone before me. We've always used a condom in sexual situations, except for oral and masturbation. What are the possible causes, STDs or otherwise, advice? Thanks.
