I am into MFM "intimacy" .. LOL ... Well I love it, I only do it with my husband and another guy, I never done it without my hubby. We both enjoy it, its nice to be the center of attention from two guys. It made our sex life much better and really brought us closer (I am talking about my husband and myself).
It can be easy and enjoyable if you get lucky in finding two guys that get along well with each other and not to compete with one another.
I am normally in total control when we start but once I see the two men enjoying themselves and started to concentrate on pleasing me, I let go and leave them to it.
Be very careful this kind of lifestyle can be extremely harmful and dangerous both mentally and physically. Choose your partners very very very carefully.
I don't know if you are married, in a relationship or single, your status makes big difference.
PM me if you are serious about doing it.
