I enjoy some cuddle time when on my way to dreamland. I think it's wonderful falling asleep in someone's arms, especially if that someone is a person you love. It brings two people closer together, gives that sense of safety and warmth. Pretty sure there's some science behind that, hormones and whatnot.
That being said, if it's a hot summer day, cuddling is not my cup of tea AT ALL. But on colder days it's amazing.
I totally understand why some people don't enjoy that though, not everyone has the same needs, it can be uncomfortable... Different strokes for different folks. Some people aren't that affectionate by nature.
My wife and I cuddle pretty much every night before we go to sleep and I always tell her I Love her before I go to sleep it's our ritual, and if it's cold out we cuddle even more. I enjoy it, I feel it brings us closer together and more intimate without necessarily being sexual, though sometimes it becomes that way, which is ok too. ;-)
I have problems sleeping, I tried it in the past and ended up hurting my partner because of my nightmares and/or my fidgeting trying to get to sleep and then waking up all of the time. I love cuddling just relaxing after sex or while watching a movie though.
I hate cuddling. Okay, well maybe not hate but I like my space as well. But I had amazing sex Tuesday night and we cuddled all night and I was surprisingly fine with it. I also get really claustrophobic so I can't be cuddled up for too long. lol.
I'm a cuddler. I like to cuddle. I will attack people for cuddles while asleep not kidding I have video evidence my friends tease me about it. Plus side I only spend time with cuddly people I don't try and force cuddles onto people that don't like cuddling it's just a requirement to spend time with me.
