ORGASM-less 😳

I've had a LOT of sex.. Hot hookups, long term relationships, even a fiancé. However, I have never achieved an orgasm during intercourse OR oral sex with ANYONE. 
The closest I've come (no pun intended) was with my ex-fiancé. The sex was MIND blowing. And when he went down on me.. Well let's just say OOOOOOOOOOH. To be frank; we screwed like jackrabbits and I absolutely loved it. We were together for 6 years and we still had sex at least 3-4 times a day. 
When we had sex, he always made sure to stimulate my clit and never neglected an inch of my body. But the only time I felt even a bit close to orgasm was when he went down on me.. But the big O still never came!
I can make myself reach orgasm.. Why can't anyone else?! Am I destined to a life of "faking it"? 😩
