orgasms

Soo.. I have never had an orgasm.. it's frustrating as f. I want it to happen so bad. i try doing it myself with my vibrator, my guy has tried and continually tries everything and anything he can do.. I feel like there are times where I'm close.. my legs shaking and don't want him to stop.. but still doesnt happen. I'm 26 and he's not the only guy I've been with. I'm so comfortable with him, more than anyone I've ever been with. we're getting married in 13 months... I just want to have a damn orgasm but don't know what to do!! someone help, guide me in some direction. 😨😭🤔👋🍆👅🤦
