I can't stand people touching my belly, not even DH unless i invite him to. A bit extreme perhaps...... but yanno.

Besides the rubbing back, or saying please don't, i find talking about how much i don't like it lets people know how i feel. My whole family know i really don't like it so now it is a bit of a joke and if a new person is around they say "go on , touch her belly, i dare ya" and everyone has a laugh, so at least it is out there!
