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.
I can’t say it’s common, and wouldn’t ever have considered asking some random good looking guy to join us, but straight guy MFM is probably more common than you think. When men on the internet talk about threesomes they seem to be thinking about 2 women, but I’ve only done the other kind and it seems like way more fun - I’m straight so nothing really exciting about adding another woman, but two guys? So many things you can do whether they are into each other or not.
I do think it’s more common for couples to approach women though, as I have been propositioned by couples and probably all women have.
