Rainboy, I may be handicapped by ambition -- the request for a final resolution led me to want to marshal all the relevant factors and make a relatively definitive post. You can consider https://www.cblf.org/messages/53509.htm
as an interim answer to your post to me, since it was written with that in mind, but I have the feeling there are some relevant points I don't have right at my fingertips, and my impulse is to re-read the new testament and a few other things to make sure I have them all collected up. Mostly things having to do with what love is and how to recognize it and where it comes from.

I wonder if due diligence also requires me to read a lot of zoophilia literature, something I have not done to any great extent. This isn't easy, since to me it is self-evident to me that zoophilia has nothing more in common with homosexuality than it has with heterosexuality. I am squeamish about the topic and I am hard pressed to make myself go there. If you weren't a boylover yourself and hadn't been there yourself, I would see it as an attempt to push me into a position of indignity and I would refuse; but since you have been bold enough to enter the wallow, I will go there with you if I must. I'm not sure there's a definitive answer to be found there, though - comparing apples to oranges may not lead to any striking new revelations.

(Whereas in bible, same-sex surrogacy and animal surrogacy are very logically placed adjacent; however, your direction leads us to discuss something quite different, namely long-term loving relationships.)

Yes, pending.
