It sounds like you've already had a frank discussion with eachother about this, which is awesome! Huge kudos to you for being preapred to experiment with him, he's extremely lucky to have you.
I'd suggest you both set some limits if you already haven't, so you're both working from the same page, he'll know how far you're preapred to go, and you'll know how far he wants you to go!
You both might not know your limits until you actually try something though, so both staying open minded will be key to discovering some limits you might not know you already have.
There's an awesome community online called Fetlife, which is kind of like Facebook but for 'kinksters' I reccomend you join! There's literally thousands of people around the world in similar situations to you that are more than happy to help!
Good luck, see you there maybe!
