Impotence

Nobody, not even us, know all the causes of impotence. It can be physical, emotional, or psychological. If it's physical, check the pulse. If there isn't any, it's dead, and has to come out.

Certain oils are claimed to induce amorous feelings. They include ylang ylang, sandalwood, vanilla, patchouli, and fokienia wood. There are probably others and we'll update as needed.
