The tendancy for a male to cuddle, or wrap around his partner is not new to women (and now even other men). Some like it and some hate it( u would not want whooping walter hudson to cuddle u!). I for sure absolutely put all my money on the bizzare yet true form of genuine affection. Well we think that cuddling is a form of expressing posessiveness, true perhaps but not entirely. Untill clothing was invented, people had very few sources of heat. so the only way they couls share, conserve or reserve the body heat was by hugging each other while sleeping. Also specially for males it was a way of knowing whether the female is awake or not.
I believe that there is so much that we males dont do intentionally but just happens because of the generations of dna that has been followed by us!
