Is it normal that i always pick rebecca goth on the sims 3?

For some reason, whenever I play the Sims 3 Pets, doesn't matter what Sim I create, I always try to hit on Rebecca Goth. I don't know why, and I don't know if it's a normal thing to do. Is it just that I'm attracted to her, or is it that I have a fetish of some kind? Oh, and my Sim's gender doesn't matter to me either, girl or boy, I'll always try to get on top of Rebecca.
