I only recently found out that mmf and mfm are literally and really two different tyrpe of threesomes. I do not like if one of my guys in a threesome is bi and pays attention tothe other guy. I want all the attention, and will never invite a guy back into my fun if he goes for mmf. I have everything they both need and am more than happy to accomodate both at the same time - I'm counting on it. Please, no bi guys doing guys.
