Taking Control, A Loner's Rise

A story how a lone introverted high school student becomes a true alpha male, conquering every beautiful woman he wants.

After a disastrous first day at school a mysterious woman comes to him in a dream and helps him achieve his lifelong dream.
Read as the protagonist changes physically and mentally and takes everything he wants.

Story is gonna be mainly about sex, but there will be some plot. The setting will contain some fantasy elements.
Protagonist is gonna be neither truly good nor evil.
It's my first time writing a novel like this so please comment and give advice.
