Orgasms

I'm 18 and have been sexually active since I was 16. I've been with men and women before and I've been eaten out for a long ass time more times than I can count, but I've never had an orgasm. I've tried just about every trick in the book when it comes to getting it done on my own, besides buying an $80 vibrator. Do y'all know the best route for me to go to get one already?
