If you have bigger lips, are you more prone to chapped lips?

I've been told many times that I have big lips (in fact, I was bullied when I was little for having them... apparantly they make me look like a duck?), and I get chapped lips A LOT. I have to put on chapstick probably 8 times a day in the summer (I get dehydrated) or else my lips get dry, cracked, and eventually chapped. Is it like this for everyone? Should I drink more water? Is it just because the size of my lips?
