Harry Potter and the world of Reversed Sexual libido (SI as Harry)

A man from our world wakes up in a world where the libido of genders has been reversed. The men are not more feminine they are just not interested in sex while women became horndogs. He understands he can do whatever he wants and day by day chooses various women to satisfy his urges by surprising them with a man who can actually get erect. Will he be able to keep up with the demand or will he genuinely try to make a cure to the men's libido so that he can have some fucking rest.
