More Interactions + Sexual Orientation Selection

Quite some time ago before all the crashing issues happened, I had my Sim Jan Ling who is married to another woman and they have a daughter visit a bar to make friends and all of a sudden she's flirting and embracing a man.

Even a woman who has about 30 female lovers visited a bar and was doing the same thing but this time she enchanted a male Sim.

So I think a preference option would be nice. If it's set to "Undecided", after a woman keeps flirting with other women then after awhile, her preference is decided.

But I would also like more romantic interactions between partners, especially differences between teen relationships and married couples.
