I am open and want to please, I have thought about MFM, and want to know are most men open to total 3 way touch and feel or is it all about the woman?

I realize everyone is different but I'm open and even excited about opening up and even helping to please me him and her. Not sure what to expect.

Obviously there is closeness is it open, is it see how it goes, or is it expected? How do the men feel? What do they expect?
