I had a drunken encounter with a lady at the bar when I was out of town. I wore a rubber but 48 hours after sex I develop a itchy rash on my stomach, legs and arms. I though it was bed bugs and used benedrl and cortizone which rash went away after 2 days. I recently had unprotected sex with my wife and after 48 hours she developed the same itchy rash, sore throat and body ache. Is this a Std Parasite Rash? What do I have because I sometimes feel itchy here and there.
