What exactly is Grero?

[Jesse1369]

 Is it when your man prefers sex with another man, but stays with you faithfully, as a bisexual? or?

Grero specifically is masculine attracted to masculine. With that said, most masculine men will be attracted to feminine (whether men or women) but at least the "attraction to feminine women" part is well-established so I wanted to primarily focus on just masculine-on-masculine.

As far as monogamy or faithfulness: http://grero.com/forum/index.php?topic=74.0
