okay i am chiming in a little late but.. chiming in is what ill do.
When i frist got into BDSM (around 19 years old) i thought of beastiality as a NO NO, hard limit, so gross, never gunna do it, so on and so forth..It was never in fantasies, it was so far out of my mind kink wise.
Then i met a boy...wait a man,that i fell in love with (online), head over heels, and he was into beatiality. We would role play a lot, and he told me that he was into this kinda stuff. I,wanting to please him so badly, opened my mind to it, and started to role play with it, it became something we would role play about all the time, it started to turn me on and really get me going.
He then asked me if i was ever presented with a situation where i could have a dog fuck me, would i do it? I had to think long and hard about it.Yes in the role plays and fantasys it was nice,fun,exciting,new, kinky and got me horny. But could i ever do it in real life? In the end my answer was 'i dont know' i cant get my mind wrapped around it,i cant see myself in that situation, and i cant imagine me doing it. So the answer would really be no, but i wouldnt rule anything out.
Him and I have broken up and stopped talking, and does the k9 fastasys still lurk in my mind? Not at all they left right along with him. I dont sit around and dream about a dog fucking me, or me doing things to the dog, or visa versa. Was i into it with him? Yes. Without him im not into it.
do i think people that have had a bestiality expierence are gross? Not at all, heck more power to ya, its your kink!
Never deny what turns you on, ever. Thats what i learned. No matter how kinky or sick you may think it is there is someone else out there that is just as "sick" or as kinky as you.
Abuse to the animal, i think not. If its a male dog fucking a female human then he wants to, he is not being held against his doggy will to fuck a human. If he didnt want to do it then he wouldnt.
