I used to be like you, Zoo.
Friends would hug me and they said it was like hugging a tree. LOL.
I think some of that stuff comes from your home life, my parents where not very touchy/huggy parents.
Anyway if you don't want to be dating then don't be, there are no set rules for what age you have to date, I believe someone on this forum said they were 17 and never kissed a boy, and that is fine, people make a huge deal out of hit, it really isn't. You do what heart says is right and you will be happy. if you do what all you're friends are doing or what you think you are supposed to be doing but don't really want to , you won't be fair or true to yourself or others.

I am in my 30's and still single.
