The male G-spot, which is the prostate gland, sits about 2 inches (roughly 5 cm) inside the rectum, toward the belly button. That’s approximately first-knuckle deep if you have average-length fingers. It’s a small, walnut-sized gland that feels noticeably different from the surrounding tissue, making it relatively easy to locate once you know what you’re feeling for.
Exact Location and How to Find It
The prostate sits below the bladder and directly in front of the rectum. Because of that positioning, you can feel it through the front wall of the rectum, the side facing your stomach. When you insert a finger about 2 inches and curl it forward (toward the navel), you’ll feel a rounded, slightly firm bump. A healthy prostate is about 2 to 3 centimeters across, roughly walnut-sized, and its texture is distinctly firmer and smoother than the softer rectal tissue around it.
The gland is wider at the top and tapers slightly downward, so it has a recognizable shape once you locate it. You’re not searching deep inside the body. Two inches is a short distance, and most people can reach it without difficulty.
Internal vs. External Stimulation
Internal access through the rectum is the most direct route because only a thin wall of tissue separates your finger from the gland itself. That 2-inch distance makes it accessible without any tools or special technique.
External stimulation is also possible through the perineum, the strip of skin between the scrotum and the anus. Pressing firmly on this area applies indirect pressure to the prostate through several layers of tissue. The sensation is less intense than internal contact, but it works as a starting point for anyone who prefers to begin externally. There’s no precise depth measurement for this route since you’re pressing inward from the surface rather than reaching a specific distance.
Why Size Varies by Age
A normal prostate weighs about 25 grams and stays roughly walnut-sized through your 20s. Starting in the 30s, most men experience gradual prostate growth. By age 40, about half of all men have some degree of enlargement, a condition called benign prostatic hyperplasia (BPH). An enlarged prostate can grow to over three times its original size, exceeding 80 grams.
This matters for locating it because a larger prostate is actually easier to find. It becomes more prominent against the rectal wall and may feel like a larger, more obvious bump. The 2-inch distance doesn’t change significantly with age since the prostate stays in the same anatomical position. What changes is how much tissue you can feel once you get there.
What It Should Feel Like
When you reach the right spot, the prostate feels like a firm, rounded bulge against the front rectal wall. It has a smooth surface and a slightly rubbery texture, similar to the tip of your nose. The surrounding rectal tissue is softer and less defined, so the contrast is noticeable.
Gentle pressure or a “come hither” motion with a curled finger is the standard approach. Start slowly, since the area is sensitive and the sensation can feel unusual at first. Some people describe initial contact as feeling like the urge to urinate, which is normal because the prostate sits right next to the bladder and wraps around the urethra.
When to Avoid Prostate Stimulation
If you’re experiencing pain, swelling, or signs of infection in the pelvic area, skip internal stimulation until those symptoms resolve. Acute bacterial prostatitis, an active infection of the prostate, is the primary situation where direct pressure on the gland can cause harm. Symptoms include fever, painful urination, and pelvic pain. Outside of active infection or injury, prostate stimulation is generally safe with proper hygiene and gentle technique. Use plenty of lubrication, trim fingernails short, and stop if anything feels painful rather than pleasurable.
