This game looks to be fun, it's the first I've seen of it, not out 'til April though and only in Europe at the moment,
http://www.benbik.com/pcgames/pcgamepreviews/singles-flirt-up-your-li... here's one review Reviewer: A gamer from United Kingdom This is already looking like an excellent game. It includes all the domestic stuff of the Sims, e.g. getting a job, making friends, but also includes adult elements which were missing from that game. Sims now take showers naked, have raunchy intimate moments and, of course, just get down and have sex. Sims who exercise and become more athletic are also more capable in the bedroom, and Sims who are more experienced can try new positions, improving their sex rating and the number of orgasms experienced. If this includes the same options as the Sims, you should also be able to put your own face into the game and your own character animations, so custom sex positions could be possible. I think it could be fun.
