When I first started dating my wife almost 20 years ago, she said to me, "I hope you're not a cuddler because I don't like it". No worries I run extremely hot. I woke up the next morning with her glued to me. "Well thats before I knew how warm you were". That being said my skin crawls when feet touch me with socks on under the covers while I'm trying to sleep.
So now we sleep like this and I would take that over socks touching me any day.
My son runs hot like me and my daughter is cold all the time like her mom. The wife was out of town for work last week, I put the kids to bed and went downstairs to catch up on some shows I know my wife doesnt really care for. While I was down there both kids snuck into my bed. As you can see my daughter has inherited the knack of knowing right where to put her cold feet.
