I must admit, I do sometimes get annoyed when people slap my shoulder. I don't mind sometimes, depending on the context, I suppose. But the other day I was talking to a friend and she was explaining a situation what happened between her and another person, and as she was explaining, she kept hitting my shoulder hard to illustrate how she felt in the situation, you know, like expression really (I know what I mean but can't quite explain it), but I was getting slightly annoyed, but didn't show it. I just thought, ''aw stop whacking my shoulder like that, it's annoying''. But everybody gets annoyed sometimes at being touched, especially repeatedly slapped when the other person is getting carried away with what they are saying.
Otherwise, being touched in general doesn't bother me. It never has.
