Thinking about it, Misaki has it way worse than MC.
MC could live a normal life if he keeps his power a secret, and if he gets into a relationship, the orgasm in demand isnt a detriment.
Misaki in the other hand, alredy has her power spread. But she would always know too much of any person in her life.
Do you really want to know the entire sex history of everyone you see?
Your family, your workmates, classmates, your boss, your teachers
Forming relationships must be hell for her, nevermind romantic ones.
