Today I noticed a small lump on my penis. It looks like an enlarged hair follicle and is next to a couple, but before today I never noticed that specific one. About 7 or 8 months ago I had unprotected sex with a girl who I later found had a case of genital warts that cleared up a few years ago, so I've been kind of worried ever since. Since I noticed the bump I gave everything a really close look and found that there is a slightly rough patch of skin close to the lump. About 2 or 3 millimeters or so in size. Its on the bottem side about 5 millimeters from the head, and is within a bunch of wrinkles along the circumcision scar. It can only be seen if I stretch the skin out, I dont know how long it has been there. I should also note that yesterday my penis came in contact with a new aftershave lotion/facecream/sunscreen. I'm hoping this is the cause. I would go and get it checked out but I do not have insurance and am laid off, so I dont know where to look. I am just trying to get an idea online if I should be alarmed. Also I have been getting about 2 or 3 hrs. of sleep for the past 3 nights, and maybe that could somehow be affecting my immune system causing something to show up. Any help would be greatly appreciated, I am very paranoid.
