Hello,

Glad to see another English chick round here!

You have done a great job so far bringing him into the kink you like, well done. Not many people have gotten their vanilla partners that far!

You seem to be second guessing what he may or may not like. He may not be as nilla as you think, he just might not want to own up to your desires as you don't.
I would gradually introduce things, you are only young and have plenty of time to explore all those things on your list with him.

Don't be disheartened if he is not into some of the things, each to their own and all that.

I suggest patience and timing when introducing new things, and begin with the softer stuff, look at porn together, watch some kink orientated films.

I hope you find a way, it will be the ride of your life and you have all the time in the world to explore this lifestyle.
