#andro-

Trixen-curious individuals don't necessarily need to be mascic/boric, they can be nullarian/a-spec. Not to be confused with nepcurious.

(Masc- / Andro - Attraction to men or masculine genders.)

I guess you could use andro-, though that usually means attraction to “”biological”” men, and tbh it’s not a very good term, as it implies all people with penises are men (andro means man/male). Gyne- would be for attraction to vaginas, in this case. But like i said, both these terms aren’t very good so honestly I’d suggest coining new ones. If you do, keep in mind that biological sex is multifaceted and extremely complicated, and that intersex people exist (and in more ways than just ‘ambiguous genitalia’).

Not specifically for nb people or exclusive, but there’s Ma-/Man-/Masc: attraction to men. You could also use Andro-, which means the same thing, but it’s problematic in that it implies that you’re only attracted to “”biological”” men.
