Perhaps you can rid yourself of Robert Drake.
I am of the belief that for at least 50 years of his comicbook existence, Drake has been a marvel character who's been heterosexual.
If he's now gay then you cannot use him because I red that you need straight heroes,
not Benjamin Russell's body with Gaveedra-7's mind who are the current Shatterstar ; bisexual and polyamorous.
I just realized something ; Isn't the marvel character Elizabeth Braddock a lesbian?
I have seen a page of a comicbook character woman dressed like Fantomex who had sexual intercourse with the marvel character Elizabeth Braddock. That means Psylocke is not straight and thus of no use to you
