lots of men like affection too, doesn't mean they love you, they may just enjoy that feeling of closeness
my bf is like limpet sometimes, cuddling me like a little monkey on my back, it feels like he's trying to get through the other side sometimes, he cuddles so intensely haha.
whenever he wakes up, and he realises there he shoots across the bed in a split second and clamps onto me.
he holds my hand, and when we are sleeping he likes our bums to touch so he 'knows i'm there' haha
he also kind wraps himself around me to sleep, at first, almost like i'm a cushion
im sure men miss all that sort of stuff when they are single too
