I don't mind people rubbing my belly, although I have to say I haven't had very many. There's the guy in the cafe who's really nice. He's married and they've just had another baby. Apart from that there haven't been too many people.

But if you're not the kind of person who likes people invading their personal space at the best of times, I can imagine it would be annoying having people think they can touch your belly without asking.
