Natural herbal supplemts or creams to induce impotence?

I am looking for ways to stop me being able to have an erection, although don't want to take hormone tablets. I was just wondering whether anyone could recommend some herbal ways of preventing erections? Is there a type of cream that you could rub over the penis to stop it from getting hard?

Anyone?

There isn't a cream or herbal remedy known to man that will stop your body doing what comes naturally.

If you truly want your cock to stop doing what nature intended, then the only way is to start the hormones (even then, that isn't a 100% guarantee that you won't get a hard on).
