What is the ruling on taking aphrodisiacs for someone who has no desire for women, and is it better for him to abstain from marriage in his situation?

It is permissible for a man to take medications that strengthen potency as long as no harm results from them. It is recommended for someone who lacks sexual desire due to illness or old age to marry, despite a jurisprudential difference of opinion on this matter, as marriage fulfills religious and worldly interests.
