the heretic genetic algorithm

This game is really growing on me. I had difficulty with the social aspects to start with - you have to make lots of friends and build lots of kudos, as opposed to skulking in your sim-house reading sim-books.

So having got into it, I now have a burning question. Does anyone know if Sims can form same sex relationships? I've been trying to get friendly with a female sim, and it seems that being romantic is an option, but she keeps rebuffing me.

So I was wondering if Sims was a strictly hetero environment, or whether I just had the wrong accessories :)
