Well I have a mod now and it has a gender preference option ....so if I start them on a preference it seems they kind of stay with it. I'm not keeping track really though. I play my sims and if I want them to be gay they are gay if straight they are straight and if they like either sex.. well they do.
I didn't mind what they did before but wasn't really aware of any change lately.. other than it seems they are more likely rejected on attempting to flirt early on. I like that change... makes it more challenging for serial romantics.
This title makes me think of "Suddenly Seymour" been singing it for two days. My family is not amused... hehe.. thanks.
