ADHD and bedroom boredom

I’m 22m with adhd and I live with my partner who doesn’t have it. I’m finding myself starting to dread ‘bedroom time’ with my partner. I find her very attractive and I love her deeply but our sx life has become repetitive. We have talked about fantasies and things we want to try however she is fairly unadventurous and only wants to try a couple things. Whereas I am very ‘spicy’ and can enjoy most knks. I’m not sure how to approach this subject with her. Of course I don’t want her to feel neglected or to end it and I don’t want to be unfaithful. I’d like genuine suggestions and if anyone else has this problem to let me know so I can feel assured in the fact that it’s not just me
