Over the summer I have engaged in unprotected sex with multiple partners (about 3 or 4 women 1-2 times each), and most of them I know and I know are clean. About 3 or so weeks ago, I started to get small, round, smooth and semi-hard bumps around my anal cavity, that resemble penis papules, but I never had any contact around that area, just vaginal penetration, and oral sex. I had no signs of it around or on my penis, scrotum, mouth or anywhere else I came into direct contact until today. I'm not sure how long it has been there, It just came to my attention a few hours ago, then I got really scared. It is a small, raised, circle like growth that is about the size of a penis papule, is semi-hard, and resembles a skin tag. When I first noticed them around my anus, I thought as a guy, I have a small amount of hair around that area, and when I wipe, I'm sure I've torn some out, leading me to believe that It could be ingrown hairs. I also went on a trip to the lake where there is no running water, so I couldn't shower for a few days, so I did begin to chafe some, and the area around my anus, and between my legs was pretty irritated and red.
The bumps are painless, I got a look at the ones on my anus first with a small mirror and flashlight, they look white, but it's very hard to tell because they are so small. Once again, I did have sex with multiple partners without protection, but didn't come into contact around the anal area. I have examined the inside and outside of my mouth carefully for anything, and I have also examined my scrotum and penis thoroughly, today I found the other growth directly under the shaft of my penis about a half an inch away from it on my scrotum... I'm scared to death. I really think this may be genital warts. Please help.
