I re-visited YBOP today after a long leave and was shocked to find that Gary has passed away. I am so sad, a great leader of a great community has left us forever. Thank you so much for revealing to me the negative effects of porn from a scientific point of view. Your work is fantastic and it really helped me. May you rest in peace.

Gary先生，真诚感谢您的付出和努力。
