Shit, I forgot – when guys say they want to be “sexually used” they almost always mean “I want you to do enjoyable things to my penis, and to have an orgasm from that.” They don’t actually mean that they want to be used in whatever way the woman wants/needs.
The Pedant has been guilty of Magical Penis thinking in the past and that may be what’s going on now, too.
Still though. Using him my way is worth a shot. We can see how it goes.
