Girls just can't do sex with a man as just non intimate, meaningless sexual gratification.

Prostitutes.

Anyway, all the girls I was involved with in my life, all were emotionally involved with me, as well. But, none of them ever faked sexual feelings for me.

Oh, and what about female sex addicts? I've know several of them in my life but I never got involved with them. I just knew their proclivities.
