Um.
I have no clue why you think someone whos first statement about Gale is "he's a huge creep" would ever romance Gale.
I literally dont want to know how that romance goes, thank you very much.
Btw even if he wasnt such a creep, I'm a straight dude, I dont care about romances with any male charaters.
I don't know about Minsc, but for all the other male companions, there are mods to turn them female.
