Canadian Mountain: rear entry on all fours, kneeling on one knee

Canadian Mountain is a rear-entry position on all fours, done on the floor or on a firm mattress. The receiving partner kneels with knees together under the hips, arms straight and hands flat, torso tilted forward with a slight arch and head up. The penetrating partner kneels behind on one knee, with the other leg stretched back and that foot on the floor, torso upright and hands on the receiving partner's hips. Penetration can be vaginal or anal, of medium depth, and the partner behind sets the pace.

Anatomy and biomechanics

The receiving partner is on all fours: knees together and bent under the hips, arms straight with hands flat on the floor, torso leaning forward with the lower back slightly arched and head up. The penetrating partner kneels behind on one knee only; the other leg is stretched back, with the ball of the foot on the floor, which gives a firm base to push from. The torso stays upright and both hands hold the receiving partner's hips or buttocks to guide the movement. The partner behind controls the rhythm, while the receiving partner can rock gently backwards to meet it. Depth is medium. The load falls on the receiving partner's knees and wrists and on the supporting knee of the partner behind. There is no eye contact or kissing, and body contact is limited to hips and hands.

Why this position works

Some couples like the drive that the stretched-back leg gives the partner behind: pushing from the foot makes it easy to vary the pace without tiring the knees so quickly. The receiving partner keeps the head up and the back free, and can rock backwards to meet each movement. Penetration is medium depth, which many people find comfortable, and the rear angle may bring sensations along the front wall of the vagina for some people, although this varies from body to body. There is no eye contact, so it suits those who like to focus on sensation.

Variations of this position

Variation 1: partner behind on both knees

The partner behind kneels on both knees instead of stretching one leg back.

With both knees on the floor, the partner behind has a wider, steadier base and tires less, but loses the push that the stretched leg gave, so the movements become shorter and gentler. The receiving partner stays on all fours exactly as in the main position.

  1. The receiving partner gets on all fours, knees together, arms straight and head up.
  2. The partner behind kneels on both knees, slightly apart, close to the receiving partner's hips.
  3. Hands on the hips to guide the movement.
  4. Use short, steady movements; place a cushion under everyone's knees if the floor is hard.

Variation 2: receiving partner on the forearms

The receiving partner lowers the chest and rests on the forearms instead of straight arms.

Dropping onto the forearms takes the load off the wrists and tilts the pelvis further up, so the angle of entry changes and the back arches more. The head can rest on the hands or a pillow. The partner behind keeps one knee down and the other leg stretched back.

  1. Start in the main position, with the receiving partner on all fours.
  2. The receiving partner bends the elbows and lowers the chest until the forearms rest on the floor or a pillow.
  3. The partner behind adjusts the height of the hips, keeping one knee down and the other leg stretched back.
  4. Start slowly, as the new angle can feel more intense.

Variation 3: receiving partner with knees apart

The receiving partner spreads the knees instead of keeping them together.

Spreading the knees lowers the receiving partner's pelvis, which helps when the partner behind is shorter or kneels lower, and gives a broader, steadier base. The sensation changes slightly because the thighs no longer press together. Arms stay straight and the partner behind keeps the one-knee stance.

  1. The receiving partner gets on all fours and slides the knees apart to a comfortable width.
  2. The partner behind kneels on one knee, the other leg stretched back, and checks the height of both pelvises.
  3. Widen or narrow the knees until the angle feels comfortable for both.
  4. Move slowly at first and adjust the pace together.

Variation 4: with a hand reaching around

The partner behind keeps one hand on the hip and reaches the other around to stimulate the clitoris.

One hand stays on the receiving partner's hip to guide the movement while the other reaches around the front to the clitoris. The partner behind leans the torso forward slightly to reach, so the thrusts become shorter and slower. The receiving partner stays on all fours with both hands on the floor.

  1. Get into the main position, with the partner behind on one knee.
  2. The partner behind keeps one hand on the hip and slides the other around the front of the pelvis.
  3. Lean forward slightly and stimulate the clitoris with the fingers, with lubricant if needed.
  4. Slow the thrusts down and coordinate them with the hand; the receiving partner says what feels good.

Variation 5: the receiving partner sets the pace

The partner behind stays still and the receiving partner rocks backwards and forwards to set depth and rhythm.

The stance is the same, but the partner behind keeps the hips still and only steadies with the hands. The receiving partner pushes back from the hands, rocking the whole body to control how deep and how fast penetration goes. It is a good way to start, especially for anal sex.

  1. Get into the main position, with the tip of the penis just at the entrance.
  2. The partner behind keeps still, hands resting lightly on the hips.
  3. The receiving partner pushes back from the hands and rocks slowly, choosing the depth.
  4. Switch back to the partner behind leading only when the receiving partner feels ready.

✓ Tips
  • Put a folded blanket or cushion under the receiving partner's knees and under the supporting knee of the partner behind.
  • If the receiving partner's wrists start to hurt, drop onto the forearms or make fists to share the load.
  • Start with slow, short movements and build up only if both of you are comfortable; the partner behind should not pull all the way out and thrust hard, because the penis can bend if it misses.
  • For anal sex, use plenty of lubricant and a condom, go slowly, and never switch from anus to vagina without changing the condom.
  • Keep talking and stop if there is pain in the knees, wrists, lower back or during penetration.

Frequently asked questions

Is Canadian Mountain the same as doggy style?

It is a version of it. The difference is the partner behind, who kneels on one knee with the other leg stretched back, instead of kneeling on both knees.

Is it suitable for beginners?

Yes, it is fairly accessible, but it puts weight on the knees and wrists. A soft surface under the knees and short breaks make it easier.

Can it be used for anal sex?

Yes. Use plenty of lubricant and a condom, start slowly and let the receiving partner guide the depth by rocking backwards.

Does it stimulate the G-spot?

The rear angle may bring sensations along the front wall of the vagina for some people, but no position guarantees it: every body is different.

G-spot: what the evidence says

“G-spot” is a widely used term for a sensitive area of the anterior vaginal wall. Scientific literature has not established a discrete anatomical structure with an agreed location, size and nature; sensitivity and response can vary between individuals.
