But I can imagine being a much younger person and having attractions to both men and women and not saying a thing to anyone. Especially not when you'd get crap from both sides of the fence.
This is the problem right there. First there is no actual study to back up what they are saying based on people who read romance who aren't in therapy. But most glaringly is the fact that they are using women who come to therapy as their source of statistics. As far as I know, and I've been in therapy, most people go into therapy because they are unhappy or discontented with something in their lives anyway. Of course they're going to bitch about something that's not right or perfect in their lives.
This is an interesting question. I wonder if it isn't because gay persons are always on the outside of things in a heteronormative world. Many have to keep their private lives quiet or they chose to so they don't have to deal with homophobia and other judgments. So maybe in fiction they can be gay and in boring, everyday jobs and lives, without all that other reality stuff coming in?
