That was in The X files episode Gender Bender. Everytime they had sex with someone they turned into the opposite gender. Except all the sex partners died afterwards.
NGL, this was by far the worst episode of that show that I've seen. It kinda ruined my binge watching of the show for the first time and I didn't watch any more for a while. There was a lot of causal transphobia that I wasn't expecting. I'm aware that it wasn't specifically about trans people but the vibes were not good.
I'm afab nb and had a casual encounter with a straight male without explaining my gender. He was shitty about consent and I do take solace in the fact that I queered him without his knowledge.
Surely the "victim" would be made bi, having started the event with a partner of opposite gender and finished with one of the opposite. Sort of a virtual threesome - just like a real threesome but without an actual third person
Quotes around 'victim' as they probably didn't notice, unless OOP was prepared and brought a prosthetic penis and wanted to be top
Ok but in the middle of - you're pretty much just gonna have to do anal because mid PIV penetration his dick is now somewhere that doesn't exist. Which is another problem altogether
