I'd have to see this neck but I doubt it. Especially if you have a cute body.
My wife's neck is very sensitive, aside from the obvious, nothing gets her going then me kissing and sucking gently on her neck, especially along the back edges, like behind the ear along her trap muscle.
Of course a NO. You watch American Next Top Model? Usually models have long neck and when they take pictures that show neck, it makes them look elegant and goddamn sexy. You shouldn't worry. Mostly girls want that feature XD
