I believe there were two sodomite characters, and they got 'married' at a later point...IIRC; they were interracial, as well. They put the 'ceremony' on the cover of the book, a la Astonishing X-Men #51.
Puke.
Marvel’s “Northstar” A canuck superdude was gay back in the late 80s or early 90s IIRC.
The whole XMen mutant thing is said by many to be a euphamism for gays being ostracized.
That can indeed be read into it if one tries.
