Re: Sexual Orientation=Psych Lim?
Most disadvantages are hooks for me, as a GM, to use to build more interesting stories for my players. The points spent in that field on the sheet are, in a way, a contract between the player and the GM. They, together, agree on what will make the character interesting and real, and promise to abide by that list, for the benefit of the story. Powers and talents and skills don't ground a character in the genre, disadvantages do.
If a teleporting martial artist character has the disad Flirtatious and the movie star beauty girlfriend of the team's brick is in the room, the character should make at least one pass at her, whether or not it would irk the brick. I, as the GM, put her there just for that reason, hoping to give the character the chance to roleplay, and expect no less.
A gay superhero, in or out, offers some great opportunities, even in the bluer parts of 21st century America. If a player wanted a character who was gay, I would use one of McCoy's values for the disad. His numbers sound just about right.
