Been there done that. It's very tricky, hard enuf to get a man and woman compatible then your half has to like their half. I'm not really a jealous type but as Joe isn't sexually active right now (trying new meds) I don't do separate swinging. I obviously have nothing against it. I find the social aspect of it can be fun, when you get to know some couples as couples and do other non-sexual things w/them, go dancing, camping etc, that part can be fun.
