So many questions Gay couple? Male 3rd party or females 3rd party?
Go to a swingers club or check fetlife
That's wild. I don't share what's mine so I could never. 😂 to all their own but I would suggest a surprise for him that's healthier for your relationship for your kids sake as well as your own. I'm genuinely not hating tho
