Firstly there are levels and levels of choking. The most soft one is not actual choking just playing with the idea of choking. Fron slight play with the hands to some objects, chokers, necklaces or anything that can be put around the neck and put some pressure but don’t actually cut the breath. Here the pleasure tends to come from the idea of submission, and it’s just a mental pleasure.

Then there is full erotic asphyxiation. Most people don’t do this for obvious reasons, as it can actually be really dangerous, people tend to prefer the idea of it (for mental arousing) rather than actually doing so. Here the pleasure have two components, the same submission and mental pleasure as before and the real physical pleasure that can come from the lack of oxygen. Lack of oxygen can make a lot of funny things to our bodies, many times similar to a drug. Mixing that with all the hormones liberated during sexual activity can lead to physical responses that can be found desirable by someone. As an asthmatic you’ll probably be thinking what the hell am I talking about funny things over lack of oxygen when asphyxiation is horrible. And while it is horrible in most cases it seems to vary depending in how the oxygen is missing. It’s very similar to hikers high or the mountain high that some people can get at high altitudes due lack of oxygen.
