For about three months we lived together and it was almost every day, sometimes more than once. Obvious exception during that particular week.
Except I couldn't find a job to support myself so I had to go back to living with parents. Unfortunately, we don't see each other very often so it's pretty much whenever we get the chance to visit. Last time I ended up falling asleep on him (literally) right after, and was asleep for a couple hours. Doubt he minded spending his morning with his naked girlfriend asleep on him
