None of my boys have ever mounted any of the girls, but Jorgie had this "thing" for Tazzer when he was with me. I'd find them on my bed or on the carpet, and normally Taz was on his back, belly up, and Jorgie was "making biscuits" on his belly and sucking on his fur. It was BIZARRE! I still think Jorgie is gay, as he always tries to make friends with any new male in the house, lol.
