how to make him orgasm?

so my partner and i have decided to stay abstinent, but we do end up having a lot of fun together. he likes to finger me and i give him a handjob. but i feel bad bc i haven’t been able to finish him yet. i think he has finished me, but i am really not sure if i just got super close or went all the way. any tips on how to finish him with just a hand job? we have done things like putting it between my boobs and thighs, but i’ve let him know that i’m not ready to give him a blow job yet. he totally respects that but i still feel bad that i haven’t been able to give him an orgasm 😔
