I am not a very sensative person, especially pregnant. I don't mind if you touch my belly or want to feel the baby kick. I don't mind you saying, "Wow! you're getting bigger" because I am and right now I feel sexier than I've ever been due to my fat rolls being smoothed out because of my stretching belly.
HOWEVER, if I look like I'm waddling, don't imitate it. LOL.
