I only feel comfortable when boyfriends hug or touch me. I can hug friends goodbye and be okay. But if someone touches me (even a friend) and I don't see it coming I jump... I feel really uneasy. I don't know why! My mother never really hugged me but she did used to hold my hand. I can't remember my dad hugging me.
Even people I like, I want to say "Please don't do that, you didn't warn me". One of my friends is really in to touching, and she's an old friend that I don't see much. I try to train myself to deal with it. That sounds nuts doesn't it?
[edit] sorry, I'm probably not helping. It puzzles me that I'm like this. If a guy at work touches me on the shoulder I flinch.. and that's not because it's inappropriate.. it's even people I like and have a laugh with. They must think they are freaking me out.
