Quick Little Vent

I just need to say something and then I'm done. But at what point of my pregnancy did I say it was OK to touch, rub or pat my stomach?? Family is one thing, but when members at my club come behind the counter just to touch my barely showing stomach AAAHHHH!!! And its not always people I am close with - but men who just want to find an excuse to touch my belly. I know it happens to all mothers, but I am really into personal space. How am I going to make it through 5 1/2 more months of this?? Especially when I'm not even really showing yet?
