How to adjust to a boyfriend being kinky.

Ive been talking to this guy. I like him alot. Hes alot bigger than me. 6'3 and ripped which makesot even more intimidating.... Hes into bondage, and pretty much everything..... how to adjust to it? It interests me but also makes me kind of nervous.... tips?

Edit: my main thing is he said hes into gagging. Which I can't do. But I wanna learn.
