ADHD, Kinks, relationship advice!

I 24(f) has been dating a man 26(m) for about a year now. A lot of aspects in our relationship our perfect but I struggle a lot with our sexual compatibility. He has ADHD pretty severe from what I can see and is medicated. I do not know too much about adhd and how that affects you sexually. His sex drive is a lot higher than mine and he wants to a lot more than I do. Which creates almost pressure for me to because I want to please him. He also is into a lot kinkier and crazier things than I am necessarily comfortable with which I have tried and continuously do but it’s just not my favorite thing (bdsm/Dom/sub etc.) he says being submissive and pain kink helps with his adhd. Besides this the relationship is perfect so I’m just not sure what to do. Advice needed !!?
