To be honest not many full husbandos to my understanding, in terms of male character I'm only interested in femboys myself so I'm not 100% sure, but probably Tetsuya as mentioned above, Brint who is an actual marriage candidate, and Berwyn. I don't think there are a lot of fleshed out male love interests. Quin might be an option once they get their expansion, also the corrupt lupine leader if you take him and his ilk in... all in all there are much more waifu's with dongs that fit the whole family dynamic than guys.
