After what had happened to him in the vampire world, Rudy tried to practice various ways to control his libido, but none of them worked. That has become a basic need of the human body for him— just like how one would need food and water at certain times.
His body, powers, and brain had adapted to that cycle, and he couldn't break it no matter how hard he tried. He could have overcome his super libido if his mental strength had been weak. However, his mental strength was increasing drastically every day, so it was impossible for him to control his super libido.
Even if he made himself a human like he did while having sex, it would work as the effect had already started. Still, Rudy tried to calm himself down, but he was slowly losing his senses, just like he did in the vampire world with Jane.
"It's not working…" he muttered.
