You'll find that there is a fetish for everything. If you're into it, chances are that someone else is into it as well.
As for me, personally, I'm not much into having my neck "squeezed" nor am I really into being choked. That being said, my neck is defiantly an erogenous zone. Being made to feel submissive turns me on, and typically speaking, the neck/throat is considered a "vulnerable" area (i.e. it contains the carotid artery). Most of the animal kingdom are wired to perceive the neck as a vulnerable spot. You just need to spend fifteen minutes in front of the nature channel to notice a pattern: predators always go for the neck. So, yeah, exposing my neck to my partner during play is one way for me to "let down my guard" and be "vulnerable." Which, in turn, helps me get into a submissive mindset.
So, getting my neck kissed is a huge turn on, or being held by the neck, or bitten on the neck. If my partner kisses/bites my neck in just the right spot, I literally lose my footing and half fall/swoon. He usually has to catch me, but it's awesome.
