If you can't control the other, I'm not sure... in the Sims 2 you could ask that person to join you if you were relaxing... Maybe it's this way in the Sims 2 too, you can try. But if you want to let them whoohoo or anything, usually if their relationship is good you can find that option in 'Romantic' too, without them relaxing on the bed first.
