The insertion depth of the dildo depends on personal comfort, body structure and the size of the dildo. Different depths of anal stimulation will bring different physical reactions. The following is a detailed analysis.
✔ Rectal length:
• The anal canal is about 4-5 cm (sphincter area),
• The overall depth of the rectum is about 12-15 cm,
• The end of the rectum is the sigmoid colon, which will cause discomfort after entry.
✔ Safe insertion depth:
• Recommended for beginners: 5-8 cm, to adapt to the feeling of anal expansion.
• Advanced experience: 10-15 cm, which can stimulate deeper nerves.
• Extreme insertion: More than 15 cm may enter the sigmoid colon, so be careful to avoid discomfort or injury.
✔ Shallow stimulation (0-5cm) - anal sphincter area
•Mainly acts on the external sphincter (controllable) and internal sphincter (voluntary contraction).
•Feeling: Slightly stretched, there may be a foreign body sensation or slight resistance at first.
•Suitable for: beginners to practice, use a small dildo or finger insertion.
✔ Medium depth (5-10cm) - anterior rectum
•Entering the rectal opening, the sense of pressure increases.
•Men may stimulate the prostate (P spot), and women may indirectly affect the G spot.
•Feeling: Enhanced sense of fullness, there may be a slight sense of expansion or stimulating pleasure.
✔ Deep insertion (10-15cm) - deep in the rectum
•Go deep into the middle of the rectum, the rectal wall has more nerves, and the stimulation is more obvious.
•Feeling: Strong sense of fullness, some people may have a slight sense of defecation (due to stimulation of the rectal wall).
•Suitable for: advanced experiencers, with lubricants and relaxation techniques.
✔Super deep insertion (more than 15cm) - entering the sigmoid colon (not recommended)
•May touch the curved area, causing discomfort or even pain.
•Feeling: The pressure is obvious, there may be abdominal discomfort, be careful.
✔Fully lubricated: The anus has no self-lubricating function, use water-based lubricants to reduce friction.
✔Insert slowly: When exploring deeply, proceed step by step to allow the muscles to adapt.
✔Adjust posture:
•Lying on your side or kneeling on your stomach can help to insert deeper.
•Lying on your back with your legs raised can make the rectum straighter and reduce resistance.
✔Listen to your body's signals: If you feel severe discomfort or pain, you should stop immediately.
