I have never had an orgasm

So I'm 29 years old and have never had an orgasm from sex or masturbation. I feel arousal that increases with stimulation, but as soon as the arousal reaches a certain point, it abruptly disappears and so on in a circle. Is there anyone here who had the same problem? Did you manage to overcome this problem? What did you do for this?

P.s. I tried to reach orgasm with hands, vibrating toys, vacuum toys.
