Orgasm

I had sex with my (now ex) boyfriend who i had been with 8 months. We did have a lot of sex and i did enjoy pleasuring him and i enjoyed close body contact and stuff, but i have never experienced an orgasm. I was too scared to say anything to him because i dont know what we were doing wrong i just sorta figured that one day it’ll click and ill have one and ill work out what we need to change so i can orgasm again. We have broken up now and i havent had sex in a long while but i really have the urge to discover what i need, i have tried masturbating and its just boring to me! and its not like i used to stress about orgasming when having sex with him because i knew id enjoy the sex for the intimacy even if i didnt orgasm. I really want to discover what i need to orgasm by myself, so next time i have sex i can feel like i know what i want/need - but how do i discover this??? What do i need to do differently???
