The prostate sits about two to three inches inside the rectum, toward the front of your body (the belly-button side). It’s a walnut-sized gland located just below the bladder, and you can feel it through the rectal wall as a rounded, slightly firm bulge. Whether you’re curious about your anatomy, interested in prostate stimulation, or simply want to understand what a doctor checks during a prostate exam, locating it is straightforward once you know what you’re feeling for.
Where the Prostate Sits in Your Body
The prostate wraps around the urethra, the tube that carries urine from your bladder through your penis. It sits directly below the bladder and in front of the rectum. That positioning is key: because the rectum runs right behind it, the prostate can be felt through the thin rectal wall with a finger.
A healthy prostate in a younger man weighs about 25 grams and is roughly the size of a walnut. It gradually grows with age. By your 40s, average weight rises to about 28 grams. By your 60s, it’s closer to 35 grams, and men over 75 often have prostates weighing 46 grams or more. This growth is why urinary issues become more common later in life: a larger prostate presses against the urethra and can slow or partially block urine flow.
How to Locate It With a Finger
The most reliable way to find your prostate is through the rectum. Here’s how to do it step by step:
- Trim your nails and wash your hands thoroughly. Short, smooth nails prevent irritation to the delicate rectal lining.
- Use plenty of lubricant. Water-based lubricant on your gloved or bare finger makes insertion comfortable. Don’t skip this step.
- Choose a comfortable position. Lying on your side with your knees drawn toward your chest works well. Some people prefer standing and leaning slightly forward, which is actually the same positioning doctors use during a clinical prostate exam.
- Insert your finger slowly, about two to three inches into the rectum. Curl your finger gently toward your belly button (the front wall of the rectum).
- Feel for a rounded bulge. The prostate will feel like a smooth, firm, slightly rubbery bump, distinct from the softer tissue around it. It’s roughly the size and shape of a walnut, though this varies with age.
If you don’t feel it immediately, adjust the angle of your finger slightly. The gland is on the anterior (front) side of the rectal wall, so you need to press toward your navel rather than toward your back. Relaxing your pelvic muscles makes the whole process easier.
What It Should Feel Like
A healthy prostate feels smooth and firm, similar to the fleshy base of your thumb when you press your thumb and pinky together. It should feel symmetrical, with a slight groove running down the middle dividing it into two lobes. During a clinical digital rectal exam, doctors specifically check for lumps, hard spots, or asymmetry on the back portion of the gland, since these can indicate conditions worth investigating.
You shouldn’t feel sharp pain when pressing on the prostate. Mild pressure or an unusual sensation is normal, especially the first time. If touching the area causes significant pain, tenderness, or a feeling of heat, that could signal inflammation or infection, and it’s worth getting checked.
The Prostate and Sexual Pleasure
Many people searching for how to find the prostate are interested in stimulation rather than a health check, and there’s a clear anatomical basis for why prostate massage feels pleasurable. A dense network of nerves called the prostatic plexus surrounds the gland and connects to the nerves serving the penis and urethra. The prostate is highly sensitive to pressure, and stimulating it can produce intense sensations or orgasm, which is why it’s sometimes called the male G-spot.
The technique for finding it is identical to what’s described above. Once you’ve located the walnut-shaped bulge, gentle pressure or a “come hither” motion with your fingertip against it is the typical starting point. The level of pressure that feels good varies from person to person. Start lighter than you think you need to and increase gradually.
Why the Prostate Matters for Your Health
The prostate’s main job is producing a portion of seminal fluid. This fluid nourishes and protects sperm during ejaculation. It’s a small gland with a quiet job, but its location wrapped around the urethra means that when things go wrong, you tend to notice.
The most common issue is benign prostatic hyperplasia (BPH), which is non-cancerous enlargement. Because the prostate surrounds the urethra, even modest growth can squeeze the tube and affect urination. Typical signs include a weak or stop-and-start urine stream, frequent urination (especially at night), difficulty starting to urinate, dribbling afterward, and a feeling that your bladder hasn’t fully emptied. These symptoms affect the majority of men as they age.
Less common but more urgent signs include blood in your urine or a complete inability to urinate. If you can’t pass any urine at all, that requires immediate medical attention because a full blockage can damage the kidneys.
What Happens During a Clinical Prostate Exam
A digital rectal exam at the doctor’s office follows the same basic principle as finding the prostate yourself. You’ll undress from the waist down and either lie on your side or stand and lean forward. The provider puts on a glove, applies lubricant, and inserts one finger into the rectum. The whole exam takes about 10 to 15 seconds.
What the doctor can assess that you can’t easily check yourself is the back surface of the prostate in a systematic way, feeling for hard nodules, asymmetry, or unusual texture. A self-exam gives you a general sense of where the gland is and what it feels like, but it isn’t a substitute for a clinical evaluation, particularly since the finger angle and reach differ when you’re examining yourself versus having a trained provider do it.
