i think any kind of sex is okay. it's sex, right? ok, maybe not rape, but consensual 'rape'. i am a sub and more than anything enjoy sex when i am being taken over and used. In other words, dominated. i had sex with our lab over a period of about six months while my husband (now ex) was overseas. It was kind of a way to get off and not cheat (though i never told him about any of it). he licked me, i sucked him. we had vaginal sex to completion. as i am sure most people here know (sorry, i'm a newbie), it's kind of a patience game, and very messy unless he stays in you the whole time (which he won't). But it was also very hot, i admit. there was a point where i would let him into the bedroom in the morning, get back in bed and he would come and fuck me like my husband used to. sort of. my point is, i don't think there was anything remotely abusive about it, it was consensual, and at times it was actually very very sexy.
