Any sex addiction is a preoccupation on lust is not helpful for
a Buddhist practice, one will be very distracted.
There are a few questions I'll like to ask; namely, how you
relate this issue to Buddhism? Which this forum is about. What is
the point do you wish to bring up? What is troubling you?
I hope you realise bestiality is very offensive to many. If you
are unable to relate in terms of Budhism, the moderator will most
probably delete your post!
Finally, I'm being speculative here, if the man, whom you use to
call darling and sweet nothings,sometimes he is cuddly and adorable
like a teddy bear and now he behaves like a pig, then that's a
different issue!
