My partner has kinks I don’t know how to execute or want to.

This is my first time being in a relationship and my partner has told me a lot about their kinks. Some of them being non con and age play. I knew nothing about these and when I looked it up what I saw was concerning. I don’t want to let my partner down especially without trying it but I really don’t want to do this. I love them a lot and I want to engage in what they enjoy but I feel like I just can’t. They have a habit of not talking to me if don’t try something but I just don’t want to. Everything in the relationship has been good so far but I’m afraid they’ll break up with me if I don’t. I don’t know man.
