My ex-wife once described how she caught her brother with their male lab in his bedroom, the dog giving him oral. And as for me, as a kid, saw the neighbor boy trying to b-f his male dog in my garage. He saw me and just continued. Asked me to try it but I declined, preferring just to watch. As a young adult, nothing. But I did have friends tell me about their encounters. (I was still "in denial" about my own zoophilic inclinations and activities in those days, which had their origin since I was at least 6 years old).
And, of course, as I've described before, it's how I discovered my wife (not ex-wife) liked pet sex, how we became an active zoophile couple. I walked in the bedroom without realizing at first she wasn't masturbating -- the dog was under the blankets between her legs, frenetically lapping away and sending her into ecstasy.
