For the record I have an interest in male animal/female human sex, yes. Mainly as fantasy really, but given the right conditions I could see taking it to reality.
"but this is just sick. "
Funny how if you make these comments in a BDSM related thread how they get tolerated so much less. Because that blood play thread, branding, and the fire play thread, or comments on snuff had nobody thinking this, I bet.
Is it abuse? Depends on the animal. Like anything else, drawing one mass sweeping concusion is doomed to total failure. Sometimes it's definitely abuse, sometimes it definitely isn't. I don't condone male human with female animal sex in any case, because proving consent is much, much harder, even for a legitimate animal expert. It's simply much to gray an area for my comfort.
In certain cases, I'm sorry, male dog to female human sex simly isn't abuse. It just isn't. Are there abuse cases? Yes. But certainly nothing close to all.
