So, I'm speaking STRICTLY about actually sleeping with your GF or BF, here. None of that "other stuff", you creeps engage in...JUST SLEEP. If you had your true preference, would you sleep alone?
Granted, I'm not a cuddly type. Based on my research (asking girls), the softest cuddling types are the "manly", hunting, "Cabela's dictates my masculinity" types. But, even if you're not a cuddler, is there any better feeling than when you're significant other gets out of bed, and you can then spread out a bit?
I've always been a "welp, okay, that's done, I'm going to go sleep somewhere else" guy. I've always just slept in a separate bed. Even before I bought my house, my apartments we're two bedroom if co-habituating with a girl. When I lived alone, I'd just go sleep on the couch if someone stayed over. It's just way better, IMO. And yeah, I have a California King.
Am I alone in this?
