Lol, Never here too! My 15 year old has been neutered for probably 13 years, he still humps the cat (actually all 3 cats, not all at the same time though), and his new game in the bed is called 'Alligator'. He gets all wound up and will start snapping at my hands. He still has some teeth left and nails me every now and then! I'm just glad that he can at his age, lol! It's the most he's played since I've had him, at 5 years old.
