There is a fine line between the two different outcomes, but we have only learned this from trial and error and by openly communicating with each other about how we feel. So, you can see why I am fairly confident when I say there is nothing wrong with you.
Everyone is different. We don't all like the same thing and we don't all react the same way to things. For some people, being made to wait extended periods of time for an orgasm is seriously hot. For others, it just doesn't work that way. In your case, it would appear that your partner seems to have become focused on the theory of orgasm control and lost sight of how it is actually working out ... which is not very well.
I really think that you need to sit down with your partner and explain to him how you are feeling. His retort that this is "all part of the kink" shows he that he has not really picked up on how negatively you are feeling about this. It is vital that you communicate this to him so that you can both work back to the place where it was fun and exciting.
Reading up on the theory of various kinks is a great way to learn and inspire new play within a relationship. The real key is adapting what you read into something that works for the individuals involved instead of applying what you read as if it was a step-by-step guide. After all, kink is about consent and meeting the needs of those involved. You do not have to consent to this part of it if it does not make you feel good. The only way for the two of you to make this work is to really talk and listen to one another. Discuss what it is about the kink that does it for you and what makes it work for him. Then, work out how that can be combined so that everyone is having sexy fun. Don't accuse him of doing it wrong, but you do need to be really clear about how you are feeling. Explain that for this kink to work for you that things need to be adapted.
