I like to sleep on my side in a somewhat fetal position.  I don't like it when my guy cuddles up with me too, Lil Me because he's so warm.  So, we often just cuddle for a few minutes before we start to sweat!  hee hee... I'm a light sleeper and often wake up when he starts to cuddle up with me in the middle of the night.  I don't mind it too much but sometimes, I can't go back to sleep.
