A few times with a fuck buddy and her girlfriend. Otherwise it has been the women concentrating on me as in FMF.
I have done it a few times I went out with a bisexual girl and we would often have threesomes, I must admit I did love to watch them pleasuring each other while I wanked.
Yes, copious amounts of times with my ex-wife and a close friend of ours. The close friend happened to be my fuck buddy, but, who was infatuated with my then wife’s body, so in the end it was rather victorious for all involved.
That was my life for 20+ years; a wife and two poly wives (one didn't live with us) and more sex than I knew what to do with, two or more times a day, every damned day (except when they had their periods). I begged them for us to add a bi guy to help me with them and get me some dick to suck but, no, they didn't want anyone but me. Best and craziness thing I've ever done and been a part of...
Many times. Enjoy my bi fb and her bi friends from time to time. Introduced her to my two bi friends once and all four of us quite a time. Hopefully we can make something happen again with a guy friend of hers because she has never had two men at the same time. I’m seeing her tomorrow and she is seeing a gal pal the next day so perhaps she can work on it with her but many of her gal friends are gay so finding a bi female has not been easy recently.
I was in a poly-fidelity relationship with two women for more than three years. MFF and FMF were a common occurrence. Kind of the same thing for us.
