I had begun translating this when other issues began to occupy my time, but here's a brief synopsis of the beginning:
The main character, Taro Kito, was stabbed by the jealous ex-botfriend of one of his sexual conquests. He finds himself facing a woman called Katya, a "guide to another world". She explains that God has given him a unique gift, the ability to "read the souls" (know the sexual preferences) of those he meets. These appear to him in the form of attributes as if in a video or RPg, for example:
The effect even works on her, to her surprise. After sex, he is sent to a world where women dominate men. The first person he meets is asked if he is the fabled savior who will defeat the Demon King. Later, he saves the girl from drowning, and winds up having sex with her mother. Afterwards, he meets Yusha, a hero, who asks Kito to join him on a quest. I haven't done much more than that, but at least you get the idea. Along the way he meets and fucks many other women in this female-dominated world.
