Sono Isekai Harem wa Seiyaku Tsuki.

Synopsis

Hayato, an ordinary high school student, is suddenly thrown into an isekai and granted a powerful absolute skill called the "Hero's Blessing." This power makes him overpowered, but unfortunately, there is one heavy price to pay: he is afflicted with a "curse" that prevents him from satisfying his biological desires alone! Trapped in a teenage body with explosive hormones, Hayato's only way to "survive" is to do so with girls. As he navigates this new world filled with girls from different races and factions, will Hayato be able to overcome this most pressing quest to save himself?
