r/ProneBone

Not many position-specific communities crack 950K, but r/ProneBone has managed it since launching in 2013. With 951,163 members as of April 2026, it's the dominant Reddit community for prone penetration content, covering anal, vaginal, and deep penetration variations across videos, gifs, and photos. Here's what actually makes this community interesting rather than just niche: the prone position is genuinely underrepresented in professional porn production relative to how often it appears in amateur content, which means this sub functions as a corrective curation space for a preference that mainstream studios underserve. The content mix skews heavily toward gifs and videos rather than stills, which makes sense given that the position's appeal is kinetic. Moderation stays medium - content that doesn't center the specific position gets removed, which keeps the feed focused in a way that larger catch-all subs can't maintain. Founded in 2013 alongside several other position-specific subs that didn't survive, r/ProneBone has shown unusual staying power. Worth noting: amateur content generally outperforms professional clips here, with the highest-voted posts often featuring couples rather than pornstar-tagged content. The limitation is that variety within the niche is inherently limited - once you've understood the premise, the browsing experience becomes repetitive fairly quickly.
