The only sexually related trouble I've ever had, is something I got from a long-term girlfriend of the "normal" or "civilian" type. She had been a regular girl having regular amounts of regular sex, therefore wasn't as careful as a professional about hygiene etc., therefore was more susceptible to getting diseases from her various boyfriends over the course of her life. She hardly ever had the first bout of sex with someone when she was in control or even sober -- she was a typical North American "I have to think it's meaningful" type, so the guys always got her drunk (me too!) to loosen her up. So, she got warts, gave me some. I had to get rid of them. Nothing major. But I've had lots of sex with lots of providers and never had any trouble (and yes I've been tested), and very little sex with very few girlfriends and gotten (a little) trouble. Makes ya go hmm ...
I always get flea bites (chiggers?) at strip clubs. Little nibbles that ITCH LIKE HELL around the top of my socks line on my shins and calves. Sometimes along my underwear line at my waist. They go away in a few days, but all those places have dirty carpets ...
