Making love at home with the wife. That seems to rather be the point of that relationship, to me at least.
Fucking otherwise. I need a certain level of emotional distance to cast aside inhibitions and indulge in hard, aggressive, ******* sex. That's not to say that I don't want any emotions involved. Quite the contrary. I'm turned on knowing that they're enjoying it, and you have to at least like them to do that. However, purely recreational, mutually pleasurable, fucking ;-)
