Help me choose the name of my new book! (Patreon)

Hey patrons! Hopefully you've been enjoying following the drafts of my latest work in progress. I'm only a few hundred words away from finishing the draft, so now I'm turning my mind to all the other things I need to have ready so I can publish it. And one of the things I need to decide on is the name of the book.

So far I've been using the working title of Best Man. I liked it because it's kind of a play on words; the bull is literally the best man at the wedding, but also proves himself to be a superior man to the cuckold throughout the story. But I know that in publishing erotica you need to make titles really obvious, especially as a relatively new author. People need to know what they're getting, or they won't take the plunge. So best man might not be quite obvious enough, because it doesn't make it clear that it's a) erotica, b) gay, or c) about cuckolding, All important things to know!

So with that in mind, I've thought of a few possible titles. I could keep Best Man but add a subtitle to make it super clear what it's about. Or I could go for something completely different. Main requirements are to keep it pretty short, and make it real obvious what you're getting if you open the book.

I'd be really keen for you to tell me what you think. Please vote for your favourite, or add a comment if you have other variations you think could work better.
