Ha, when I have sex with my wife, I only care whether she is a willing participant,  To the extent that she enjoys it just increases my pleasure, but that is an ego thing more than it is an unselfish loving act on my part.  The fact is, neither my wife nor I require sex in our marriage, except that it was the way we conceived our children (a very big deal).

The unifying aspect of sex, imo, is the pleasure given to the man makes him less likely to go looking for sex from another woman and for both parties to threaten the end of sex if the other is caught with another.
