ELI5: Why does it feel like I'm being choked even when something is just barely touching my neck?

I would venture a guess at natural defense mechanism. The throat/neck is one of, if not the most vulnerable parts of the human body and one of only a few which can cause death when applied only mild to moderate pressure to. 

It would make perfect sense that our bodies know this and don't like it when it feels this weakness is being exploited.

And addressing the clothes comments here. The brain has the power to ignore constants. If you leave your clothes on for long enough you forget about them, even though you are very aware of them initially. The same would apply to the neck like the rest of the body.
