An
exercise in
ascetic engineering. First, find a
refuge from sex. Minimize
social contact that has historically
led to sex. If necessary, put the word out that you are not
available for sex.
Remove reminders of sex from your refuge, and from all the places you frequent, as much as possible. Wear clothing that does not remind you of, or stimulate, your own sexuality. If and when you find yourself thinking of sex, firmly tell yourself to "Stop!" and replace the sexual imagery with something nonsexual, such as a relaxing beach or mountain scene.
Consider how best to sublimate and channel your sex drive into something productive and/or artistic. Libido will express, it is up to you to rule it, or be ruled by it.
