I think it's a natural reaction hun, i'm the same. I find myself just putting my hand over it, sometimes even when i'm at home. Guess it's a comfort thing as well as a protective instinct. I've been going out to pubs/bars stuff quite a lot still (i used to be a regular Saturday night party-goer before i fell pregnant and have still been trying to do the socialising side without the drinking) but i think i'm going to have to knock it on the head soon. I just get really panicky around crowds, especially when people are getting drunk and lairy. Best to avoid certain situations i think x
