Welcome back to the forum. However, in looking at your recent discussion with Dr. Hook, this question was really answered by him. STDs are not transmitted by means other than direct sex. With rare exceptions, that means penile penetration into another person's vagina, rectum or mouth. Even oral sex is low risk for all STDs and zero risk for some, and you didn't even have that. Body contact and hand-genital contact carry no appreciable risk for ny infection, and not STDs can be transmitted through clothing. You could not have acquired any STD from the events described and you do not need testing for anything. The bump on your thigh undoubtedly has nothing to do with this event.---
