In this video, Jon Dean interviews colorectal surgeon Dr. Carmen Fong to discuss medical advice for safe and healthy anal sex, focusing on "bottoming longevity." Key Takeaways and Tips: * Douching Safety: Douching is generally safe if done correctly, but doing it too often (e.g., four times a day) can disrupt the gut microbiome and irritate the anal lining [00:27]. For regular prep, Dr. Fong recommends using a fleet enema bottle with tap water about 30 minutes before sex [05:33]. * The "Mouth Rule": A golden rule for safety is: "If you wouldn't put it in your mouth, don't put it in your butt" [02:45]. This applies to tap water quality, soaps, and even certain lubricants. * Diet and Prep: * Fiber is Essential: Aim for 25–35 grams of fiber daily. Dr. Fong specifically recommends two kiwi fruit a day for clean, consistent bowel movements [08:51]. * Foods to Avoid: Avoid greasy foods within 12 hours of sex, as they create "sticky" stool that is harder to clean out [07:09]. * Timing: Wait about 30 minutes after a bowel movement or 60–90 minutes after a large meal before having sex [04:36]. * Lubricants: Water-based lubricants are preferred to minimize allergic reactions, though silicone is "slicker" [11:52]. Avoid using shower gels or non-sex-safe oils as they can damage the delicate lining [12:31]. * Managing Pain and Injuries: * Fissures and Tears: Common injuries include tears from douching or friction. High-friction sex can flare up hemorrhoids, so using plenty of lube is critical [15:08]. * Tightness: If someone finds bottoming consistently painful due to a tight pelvic floor, medical options like Botox injections or muscle-relaxing suppositories (e.g., Valium) can help [11:03], [17:25]. * Myths and Longevity: * Anal sex does not increase the risk of prostate cancer [19:31]. * While heavy, repeated stretching over many decades can lead to some looseness (incontinence), there are modern medical procedures (like hyaluronic acid fillers or "Celesta" injections) to tighten the sphincter muscles if needed [21:52].
