Should one abuse them? No. But is it wrong to have an ice cream cone with no regard to nutrition? Is that the sin of gluttony?
A pure man in perfect union with God no doubt eats, sleeps, and procreates as an expression of divine glory. That is the ideal. But an ordinary man can have a hint of the divine when he has sex, and I think that is only for the good.
"A hint of the divine"? What does that mean?
When "an ordinary man" (by inference, one that is NOT "pure...in perfect union with God") has sex, what does that have to do with God in his mind?
And no, invoking His name in the throes of passion doesn't count.
