Afraid of intimacy

Actually for long I have been avoiding any emotionally intense situation .. when a friend tells me he thinks I am the best he has ever met or when he uses these intimate friendship stickers on facebook chats .. it just makes me feel disgusted . Another thing is when mum tries to kiss me or hug me or so or when I have to help someone through an emotional dilemma .. the same feeling I may do that but even still very reluctant .. I can't even call anybody I know a friend and my brother I keep telling him I don't care about u u r not my brother but in the deep I care .. but it is just the disgust of intimacy . What is that ?

Have you ever had soemthing happen to you that may spark this fear? Or some people may just be asexual and have no desire to engage in intimacies with another person. Some people don't like to be touched. It's not neccessarily a bad thing.

Don't know .. can't put hands on sth specific .. but what is it like to be asexual?
