I hate mine being touched too.. it just feels really weird and uncomfortable. I think its gross.. lol ahh so gross. Just the thought of somebody putting their finger inside of it creeps me out. >.< I even had an ex who would purposely do it just to bother me.
My boyfriend is kind of like that. I detected it early, so he doesn't actually know many of my pet peeves because he would just mess with me if he did!
