91Porn is a Chinese amateur tube site built around user-uploaded homemade content. The platform enforces a self-shot upload policy and attracts around 31 million monthly visitors. Guest users can watch up to 10 videos per day for free; VIP memberships at $45/year or $95/year unlock higher daily limits, HD viewing, ad-free browsing, and download capability. The site has significant usability issues: ad density is high (even with an ad-blocker active), video thumbnails are small, and there is no mobile-responsive layout. The claimed HD quality for user-uploaded videos is described as uncertain. Best for users specifically interested in authentic Chinese amateur content who can tolerate the cluttered interface.
