What is the low on a guy's psychological thinking that makes him want to watch sex in particular men fucking my ass...

lmao...that sucks! Not sure why or anything though...just a kink I guess

Ewww. That's a kink all right, but because it involves something like that it sounds like it is one that would end a relationship, that is unless you like doing stuff like that.

For background, some fetishes start out because of incidences in childhood others manifest sometimes with no reason in later life usually early adulthood. That particular one, well I can't see what is behind it (I don't understand men that like to watch their partner with others)

I have a bit of a fetish: girls in snowboarding gear, like snowpants etc, and oh my god, those cute snowboarding boots drive me up the fucking wall!
