Seems I agree with the general consensus here. I'd like to be a part of the experience together, not replaced or feel cheated on if I find out it's a secret. He just wants to mount...but then so do many cheaters trying to score. Chances are I'd be okay if it's a mutual agreement, especially a dog over another guy, but I'd like to be a part in some way. If I'm out of town on a work trip, share the moment with me in some way: phone call during, live session, etc. Turn me on wanting you even more for having done it. If I come home from work and you didn't wait for me to share in the experience, greet me by showing him running down your legs with your innocent sexy smile. There's a good chance I'll pounce you right there. I had an ex once that would turn my advances down, and then told me she was curious about going to a swingers club. You don't want to have sex with me but I'm supposed to be happy letting other men? Turned out she was cheating on me. If you turn down your partner for another, human, dog, dildo, in a sense it's all cheating then and to me not a partnership.
