Individuals who engage in receptive anal intercourse (bottoming) or use dilators, persistent tightness, involuntary muscle spasms, or severe pain can turn intimate moments into a source of stress and physical discomfort. Dealing with conditions of the colon, rectum, and anus can feel uncomfortable, stressful, and difficult to discuss, but patients do not have to navigate it alone or in silence.
Led by Dr. Zuri A. Murrell, double board-certified colorectal surgeon and Director of the Colorectal Cancer Center at Cedars-Sinai, the practice prioritizes helping individuals find comfort, restore their quality of life, and regain self-confidence in a warm, compassionate, and completely judgment-free environment. One of the most effective, cutting-edge, and non-invasive solutions offered for hypertonic (overly tight) sphincter muscles is Botox for Bottoming.
The Anatomy & How Botox Works
The anal canal is governed by the external sphincter (which is consciously controlled) and the internal sphincter (which maintains baseline resting pressure). When the internal sphincter becomes hypertonic or chronically spasms due to stress, pelvic floor dysfunction, or past tearing, it refuses to relax during penetration. This causes sharp pain, friction, micro-tearing, and reflex tightening, creating a painful cycle where anxiety and physical resistance reinforce each other.
Botox (botulinum toxin) breaks this cycle by temporarily blocking acetylcholine, the signal that causes muscle contraction. When precisely injected into the internal anal sphincter, Botox relaxes involuntary muscle spasms, lowers resting pressure, prevents painful tearing, and improves localized blood flow to heal tissue, all without affecting conscious bowel control.
The Procedure & Timeline
At the practice, patient care is tailored to unique anatomical needs in a private, supportive setting:
- Quick & Non-Invasive: The 15-to-30-minute procedure uses local numbing agents or mild sedation to keep patients entirely comfortable while precise micro-doses of Botox are administered directly into the internal sphincter.
- Zero Downtime: Because there is no cutting or tissue removal, patients can return home immediately and resume daily activities right away.
- Progressive Results: Localized soreness resolves within 1 to 3 days, and the muscle begins relaxing by days 5 to 7. Peak relaxation occurs between weeks 2 and 4, significantly reducing penetration resistance for 3 to 6 months. For many, breaking the spasm cycle allows the pelvic floor to permanently relearn relaxation.
Restoring Comfort, Pleasure, and Confidence
While Botox is a low-risk treatment, the anorectal region is intricate. Receiving treatment from a specialized colorectal surgeon ensures exact dosage and placement to achieve optimal muscle relaxation while safeguarding full control.
Pain or tightness should never hold anyone back from a healthy, fulfilling intimate life. With decades of specialized experience as Director of the Colorectal Cancer Center at Cedars-Sinai and a trusted provider across Los Angeles, Beverly Hills, and Los Alamitos, Dr. Murrell delivers best-in-class surgical expertise paired with a warm, gentle bedside manner.
