I truely enjoy watching other men as they play with Kat, but I take no interest in playing with the male. With that said, there is something very exciting about watching a man cumming as apposed to woman. I think most people assume that the male in the couple would have to be just as interested in the man as he would be with his wife and I don't think that is the case in most couples.
Do you play straight as well? What I mean is if the couple is straight but likes you the bi part may scare them if you are trying to meet all types of couples and are fine with straight play make sure you tell them, you can play straight if they like.
When we first started swinging we insisted on straight so we would not add another dimension to the lifestyle until we knew if we liked it. And most are swinging was MFM . I never had an issue with close proximity to another male (it's sex you don't have a choice sometimes) that's just how we felt. We now have a very close friendship with a couple that has shown me what In have been missing now we are open to go if all parties are interested.
I Have been straight all my life, and was kind of oooooooh wouldnt touch the male,but one time it ended up in some male touching. And I admit it wasnt all bad in the heat of the moment. Since then, and as I am getting older, I am becoming more curious(wouldnt say I am bi) and in the heat of the moment, if it feels good, go for it. I do respect the guy if he is not into it at all.
