I'm embarrased to admit this, but I kinda like playing The Sims
Rana, to make your Sims do woo-hoo in bed, first of all get a bed that can hold two. Then in the evening, ask your female "friend" to spend the night, then go and REST on your bed. Don't go to sleep though, or take a nap. Then, invite your friend over. Ask her to sit down on the bed, and start making out. P.S.: admins, if this is getting too weird, let me know...
. Anway, keep on doing this, and sometime later, an option for woo-hoo will appear. You know what has to be done next....
Till the next time,
your friendly neighbourhood pimp...
