Always about coherence:
1) My current Tav didn't flirt with any other character than Laez'el. Still Will and Gale (with both of them my Tav had high approval) proposed, and they did also in a very blunt way. Why? I don't give a dime about the herosexuality (even if it feels quite irrealistic, sexuality is one of the things that contribute to ones person individuality an duniqueness), but it doesn't make any sense that they propose. They look just as horny morons controlled by their lesser brain and not by their actual one.
