Hi,
I'm a 26 year old gay male in good health with no history of STDs. When I awoke this morning, I felt some itching. I didn't think anything of it, until I inspected it right before taking a shower. I saw possibly 50 little red bumps going along the ridge of my "happy trail." I shaved the area afterwards to get a better view of the irritated skin. It seems the bumps are all surrounding hair follicles. It's not extremely painful, just itchy. I don't seem to have irritation anywhere else.
I had unprotected sex with a childhood friend, someone I don't know very well, the night before last night. This was our first time doing so, and I was mostly the "top." I'm fairly certain that whatever this problem is, it's related from that night. I don't have sex extremely often.
These bumps were non-existent last night. It's not razor burn, because I hadn't shaven for days. They just formed while I slept. I'm guessing this is an STD of some type, possibly herpes but hopefully something temporary, but don't know enough about this stuff to make an educated opinion.
In the following image, you'll see my navel at the upper extremity and pubic hair of the groin at the lower.
