I had unprotected sex with a girl two weekends in a row about 3 weeks ago, after breaking up with my girlfriend of over a year. Now I have noticed an itching/burning sensation which started on my thighs one morning, and is now mostly in my pubic hair region. Its been about a week now, and I see no signs of anything else. Could this be the initial stage of herpes? I was thinking maybe jock itch but there's no redness or bumps of any kind. The girl is in watersports so she is in the water a lot in a wetsuit most of the day, thought that might be a clue to a yeast infection like jock itch of some kind? Any ideas what I should do?
