Okay basically ive been with my girlfriend a good few months now and we always used contraception ( condom ) but about 2 months ago she started using the pill so now we obviously are not using a condom. A few days ago i notice a redness under my forskin and like 2 red dots on the Head ( mushroom ) it looks like a rash but just dots... it causes no pain what so ever and ive never noticed it before im very concerned that i could of caught a STI from my GF but i really hope not.

Any ideas on what this could be would be highly appreciated
