No I have not had intercourse with another man since my husband and I started dating 5 years ago, But before that it was my 1st husband, boyfriends and a few one-nighters.
Personally I find intercourse 1. too intimate to engage in with casual aquaintances 2. Dangerous (condoms are not foolproof.....I have twice had one either break or come off) 3. Not all that pleasurable with other men (I am deathly allergic to latex, plus it is not any spectacular sensation physically for me (yes I have been with Large, average and small men) So I say why bother? Even in our marriage we rarely have intercourse, it takes my husband WAY too long to orgasm thru intercourse and I end up raw and sore....To me, a gangbang sounds like absolute torture!
As for my interest in male Bi, yes, I bring it up to my husband often. Sometimes in a teasing way or just to open up the topic. My best friend in the world is a Bi (90pct gay) man and I am trying to arrange a night out for the three of us
.......also, my husband has a good friend who is actively bi. He usually laughs about it.......I have even rented Gay porno's. He says I will have to get him drunk, which is a joke because he is a non-drinker. But no, I do not think he is interested. But I don't think I am doing anything different than a man would do with his wife....i.e. rent porno's with bi scenes, etc.
As for male bi not being accepted, I have NEVER seen it take place at a swing club. I have seen some swing clubs where the website SAYS no Male bi activity allowed! But in the clubs we have gone to, it is not a stated rule but believe me, it would be very unacceptable. Im sure there are some couples outh there with a Bi male but they probably would just tell you about it on a one to one basis.
To me, that would be the ultimate threesome, I have fantasized about it since I was a kid. But a MFM threesome where I am getting all the attention and the guys avoid each other........leaves me ice cold
