Why are you so convinced that having sex with a woman means that you are "demeaning" the woman - or that it would be something desirable by most men?
Also: giving pleasure to your sexual partner is probably the most enjoyable and gratifying part of sex. Of course, only a non-virgin would know that.
The point is that women enjoy good sex as much as any other guy (regardless of his motives), we don't think it's demeaning or humiliating or anything of the sort. What you are referring to is called "rape".
