If she knew he was a virgin, she should have explained to him beforehand what she liked sexually and should break him in slowly to her process of pleasure. Too much of kink at once, with a newby can lead to horrible miscommunication and probably leave a sour taint on the sexual relationship and would probably block him severely from trying anything new with future problems. Now, I'm no sex therapist but this would be my view from experience.
