nipple sensitivity?

Alexis
Okay so I have this thing that I'm not sure if it's normal and if it is oh well but when my partner tries to tease me with his mouth on my nipples, I can barely feel it. Like I don't get a rush of excitement or anything unless he bites down on it and then I get a rush but besides that I get really bothered when he does it now and it's like I know I've told you they need more pressure and he insist on cute little pecks and sucks like I can feel that. It is definitely a pet peeve of mine. Is anyone else out there have this same problem too?
