Aren't both parties cheating in this situation?  The wife is not only having sex with someone besides her husband, but it is homosexual sex also.  Does that make her in the wrong twice as much or does it not count as cheating at all?  Just a thought.\n\nAs for the man, yes, he is cheating, but with permission.  It's not a glorified way to cheat, it is approved cheating.  What can the wife say if she is also having sex with the third party?  \n\nFor the most part, men have this fantasy to boost their ego.  The idea that they can satisfy more than one woman at a time and then try to prove it correct is just huge to men.  As for who the two girls are, it doesn't matter.  As a matter of fact, I think that the man would have even more fun if neither one of the women were his girlfriend or wife.  This way he doesn't have to concentrate mostly on one woman.
