I don't wanna post sources because I'm on my work laptop, but I've read conflicting reports stating that the clitoris and glans have roughly the same number of nerve endings. Still, we have more nerve endings contained in a tiny space, so yeah. You'll probably notice if someone's chompin' down there, but if that's what you're into (which, let's be honest, we all are), then keep on eatin', brah.
Wait, shit, we were talking about labia. Fuck, just eat it all.
