I need to ask a question. I know as part of the NoFap challenge one is not supposed to watch porn. But I have documentaries on sex and tantra which I hope to learn as part of self-improvement. I already have them and hope to watch them as I havnt watched all of them yet. The purpose of sexual positions is not for entertainment but for education and self-improvement purposes. What do people think about this? Will watching sex documentaries and documentaries on Tantra be violating the NoFap challenge under pornography?
