I've no doubt that he just had performance anxiety because he liked her so much. It may have hurt her, but I've also no doubt it was also a self-esteem killer for him too as a "man". I don't know what sex education is like in Japan but man, I wouldn't be surprised if he had erectile dysfunction for a while (or still does) knowing how conservative Japanese society is when it comes to suppressing sex talk. The girl should also look into therapy.
