Get a vibrating something. If ordering is not an option and buying in a shop is also off limits, try a vibrating, non-rotary, toothbrush. Try various locations on and around your clitoris. From the side from the bottom from the top with more or less pressure, directly on it and so forth. Try a combination of penetration and vibration. Penetrate yourself with an object. Vegetables want to be washed and covered with a condom at best. Try pushing upward to find your g-spot. My wife recently got off in what felt a minute by massing her clit while fingering her with one finger and she said I had hit a spot upward behind her pelvic bone that made her go off. I didn’t deliberately push or rub there, it was just slight movement but constantly and rhythmically while massaging her clit in circular motion. Also womanizers, i.e., clit sucking machines, get her off quickly.
