Here's one of the most famous Star Wars kisses, when Han Solo and Princess Leia kiss in the underground rebel base on the ice planet Hoth. She kissed him and everything, but she made it clear along the way that she would rather kiss a wookie.
It appears that she knew what she was talking about:
Awww, here she's getting a kiss from Lando Calrissian. Okay, okay, that's enough.
Oh yeah, here's a famous moment, too, where Leia passionately kisses her brother to make her future boyfriend jealous. So jealous.
It also led to this awkward family moment on the new Death Star:
Basically, the point is that I'm not sure there are enough women to go around in the Star Wars universe.
But I'm sure Lucas can change it and update it in the next version of Star Wars. I hear there are a lot of changes coming, which should be fun!
