I'm too nervous to do anything with my bf when we are making out because I have braces help?!!!?

so i am 17 he is 18. We have been together for 7 months and we are in love, but we havent done alot sexually. he is always the one doing things . anyways but now he is always asking me what i want to do or if theres anything i want him to do. i really have tried to think of things but i just cant. im always too scared to do anything (especially kissing cause i have braces. not like normal kissing but other stuff cause ive accidentally cut his lips a few times and since then ive been scared to hurt him again) i just dont feel sexy at all, i feel like im 13 yr old braceface but i know im not. and so i dont wanna do anything. how can i feel more sexy and get more comfy with the fact of doing things to him back (but not actual sex!) ? also what could i do any ideas? i wanna start small so dont say handjobs/blowjobs please!!!
