With MFM, the difference between the sexes is smoothed out.

[Truwor]

My wife and I’s friend and lover taught me that during a threesome, the difference between the sexes is smoothed out, and that sympathy between men is no less important than sympathy between men and their woman, and maybe more. Men should caress each other as much as they caress their woman, trying to please each other. And since the husband allowed another man to be with his wife, then he should caress the other man just like his wife. It seems that everything is logical, but it is not so easy to agree and accept it.

If these two men are bisexual, then there are no particular problems with caresses. Of course, these caresses may not be the same as with a woman, but the practice of this format will put everything in its place.

MFM is good when two M are both bi, there are many more options for sex
