Ok, but here’s another sticking point for me. Sure he’s old. Not attractive to my way of thinking.
But he, and others like him I’m sure still have wants and needs. Does being older preclude him from physical intimacy?
It’s grosser because he’s an old guy?
If you can’t figure out the answer to that, then you have a problem
I think it would be ‘gross’ no matter who or what age he was - or if a woman did it.
