You guys act like you could handle her libido but I don't think you truly understand what you're asking for.

This girl has been training as a classic idol since likely her teens. And she is very committed to the role. You are talking about quite possibly years, if not a decade's worth of sexual repression to maintain the idol persona each and every day. You think she'd care about your refractory period once the damn is broken? No. She'd take everything from you until your balls couldn't produce semen anymore, then she'd just keep going.

You don't want this. She is too strong for any mortal man to handle. You wouldn't be having sex with a woman, you'd be releasing the biblical incarnation of lust.
