I've been involved for about 6 years. Started out as a single woman, then a couple for a year, then single again, now again as a couple for the last 2.5 years. He had some interest in it and had joined the yahoo group that I was running. He and I had gone to high school together and I'd had a crush on him way back then. We've been together since and swinging from the start. We took it very slow for the first year while we built our relationship and really did nothing more than run around naked at our pool parties and some very mild flirting. We have progressed to a full swap couple, although technically I don't know if you could say that as I've never actually been penetrated by another man LOL Not for lack of trying...it just seems like it never gets that far for one reason or another. We've not had very many playmates because it seems like either we're interested in the girl, but not the guy or I'm interested in the guy but not the girl and we're not willing to "take one for the team".
