Given that the exact same question is the current top post but for driving instead of transit, I feel this question was needed.
My answer: I saw some guys hooking up a Raclette Grill to the outlet in an otherwise empty German intercity rail waggon. They had it unpacked in one of these 4 person seats with a small table. No idea if that could work or if draws too much power from the board net. I just headed on to the next waggon.
Wild take at the end of a comment about being overtly sexualy kinky in public
I do though. I think it sucks the human connection out of sex and numbs people to their feelings. I think people who are into it are using it for passive self injurious behaviour.
I read this article about a woman who was killed in bondage in a BDSM household where her “master” who killed her had a few other “slaves”. All the women were fairly chubby and said when interviewed they hadn’t had many relationships before, it was obvious they were super vulnerable and in the hands of a sociopath. At first they defended him and covered up for him, but then came forward to the investigation and told the truth about what their household was like.
I’m not saying that playing around with a little kink isn’t ok, a spanking for example can be quite nice. And whatever I might think, you do you, just be safe and have self respect, and leave strangers in public places out of it.
