Continue to touch post orgasm.
Our genitals are hypersensitive after we orgasm. One way to increase our tolerance for sensation is to play in the extreme ends of it. Stroke, tickle or touch your genitals for two minutes post orgasm. It doesn't have to be full-tilt, just go soft and easy to a level you can tolerate. Feel what you feel.
