If you don’t want people to eat your genitals, have you considered filling them with deadly alkaloids and neurotoxins? Alternatively, just make your genitals look deeply diseased and likely to kill anyone who breathes near them? These methods seem to work pretty well for most mushrooms.

If you’re absolutely determined to make sure that no one eats your genitals, and you don’t want to learn from the mushrooms, I would recommend registering as a Republican.
