I soooooo get this!~ We have a queen sized bed and a decent mattress. I can't fall asleep without my hubby beside me, but I can't stay asleep when he's there. I get too hot, he encroaches on what I see as my space. If I wake up and he's sleeping, he's snoring. Oh, and he's wacked me more than once in the face while dreaming (unintentionally).

As for sex, I can get that anywhere in any room at any time (well not the kitchen, that's unsanitary).

I don't kick him out, he usually leaves by 3 am because my menopausal ass has the fan on and it freezes him out. Win-win!
