I agree with this 100%. I find any pressure on my neck one of my biggest turn ons. Even in past Vanilla relationships I always hinted that they should grab my neck. Breathplay for me is literally like saying "take my life in your hands." It takes a lot of trust, but I've never done it to the point of passing out.
It's a total lack of power and one of the most vulnerable locations on my body, it get's me off like you can't imagine.
