Request: Lovestruck auto sleep cuddle in bed.

Hi everyone. I love how sims can cuddle in bed with this expansion. Problem is that they won't do it autonomously. Sometimes they did on their own when one of the couple already in bed sleeping but most of the time i had to do it manually. Can anyone make a mod that make it always happen autonomously? I love how sims 2 and 3 did it automatically everytime the couple sleep in bed.
