I have been propositioned by swingers quite a bit. It’s to the point that if a couple is nice to me, I start getting suspicious. This has happened with acquaintances, long-time friends, people I’ve met at a party, co-workers, and even strangers at the beach. Three times that I can remember off the top of my head, they propositioned me and my girlfriend at the time (separate girls many years apart). Is this a normal thing? What about me could make me attractive to swinger couples?
I’m a cis-gendered straight male. As far as physical attractiveness, I would say I’m slightly above average based on what women have told me and how they treat me.
When I was late teens and early twenties, I kept getting propositioned by gay guys. It started to bother me - I’ve never been in any way homophobic, but I’ve also never been attracted to men - and I started to worry that there was some vibe I gave off that made people think I was gay.
Then I mentioned it to a gay guy who I knew, and he said that the vibe I give off is of someone who isn’t judgemental and who wouldn’t react badly to being asked. Maybe there’s something similar or analogous to your situation.
Edit: propositioned, not preposition
