I worked in a gay sauna for many years, yep, it's a sociopath. And usually a guy who was venting frustration at not getting off. Had 1 guy who would carefully leave a shit in a bowl of urine, (infact usually several of them) the bowls were there for the used condoms...allways really annoying as you'd have to fish the condoms out before flushing the mess down the loo. It was gratifying when you tracked down the culprit, and could throw them out and ban them with lots of loud verbal abuse, name and shame I say!
If I have a random fuck somewhere, I always send an exploratory finger in first, if it hits log, I'm out of there and washing the shit off. Had shigella recently, and am a lot more choosy where I stick my tongue. Pity as I like rimming, REALLY like it, lol.
