I'm not sure what it is about straight sex on film or even in writing that I don't care for. Maybe it is just the way it is typically portrayed. I don't hate it or anything, but it is rarely a turn on.
Most everyone I know knows I have a thing for gay men and sometimes women... lol. The way I look at it, nobody thinks twice when a straight man likes two women together, why wouldn't I, a straight woman, think that two men are hot?
On the other hand I do think there is more to it than that. And it seems that there are a lot of straight woman that feel the way we do. I find it really interesting...
