been faking orgasms for a year

(F20) I love my boyfriend and we've been dating almost 3 years but only been sexually active piv for one. He's so perfect in bed and is doing everything right but I feel like it's impossible for me to have orgasms with penetrative sex, i'm also too scared to tell him ive been lying about him making me orgasm for a whole year, id like to add ive also never been able to achieve a penetrative orgasm on my own either, what am i doing wrong?
