Flatiron sex position illustration - A flat, face-down position for gentle, grinding sensations.
Penetration: Deep
Stimulation: G-spot

About This Position

The receiving partner lies flat on their stomach while the penetrating partner lies on top and enters from behind. Like the flatiron building, this position is sleek and streamlined, offering deep, grinding sensations.

Best For

Deep penetrationRelaxationGrinding

Clitoral Stimulation

Limited clitoral stimulation from the position itself, but accessible with a hand.

The receiving partner can reach their own clitoris or the penetrating partner can use a hand.

G-Spot Stimulation

Good G-spot stimulation from the prone position angle.

The angle creates a natural curve toward the G-spot.

Anatomy & Physiology

Muscle Groups Involved

  • Glutes
  • Lower back
  • Hamstrings
  • Inner thighs

Angle of Penetration

Slightly downward, deep penetration with grinding motion

Targeted Pleasure Zones

G-spotDeep spotCervixClitoris (with hand)

Body Contact Points

Full body contact along the backChest to backPelvis to buttocks

Step-by-Step Guide

1

The receiving partner lies flat on their stomach on a comfortable surface, legs together or slightly apart. The prone position creates full-body contact along the entire back.

Tip: The G-spot is rated 4/5 — the prone angle creates a natural curve toward the anterior wall.

2

The penetrating partner lies on top, entering from behind. The slightly downward angle targets the G-spot and posterior wall through the grinding motion.

Tip: A pillow under the receiving partner's hips improves the angle — the hip elevation is key.

3

Use a grinding motion rather than thrusting for deeper sensation. The glutes and lower back drive the grinding — press the pelvis forward and rock.

Tip: The grinding motion creates sustained internal pressure along the G-spot area.

4

The full body contact along the back creates a sleek, streamlined experience. The chest-to-back contact point provides warmth and intimacy.

Tip: The receiving partner should breathe comfortably — check that your weight isn't restricting their breathing.

5

The receiving partner can adjust their leg position — spreading legs wider creates more space for deeper penetration; keeping legs together creates tighter friction.

Tip: The inner thighs and glutes are engaged to control leg position and angle.

6

Rock gently together in a slow, rhythmic motion. The flatiron is about smooth, grinding pleasure rather than powerful thrusting.

Tip: This position is rated Easy difficulty with no joint stress — ideal for relaxed sessions.

7

Use hands to caress the receiving partner's back, hips, or reach around to the front for clitoral stimulation (rated 2/5 without manual help).

Tip: The receiving partner can use their own hand for clitoral stimulation from the prone position.

Safety & Precautions

Warnings

  • ! Avoid putting too much weight on the receiving partner.
  • ! The receiving partner should be able to breathe comfortably.

Modifications

  • * Place a pillow under the receiving partner's hips for a better angle.
  • * The receiving partner can slightly spread their legs for easier entry.
Flexibility: Low Joint Stress: None

Not recommended during pregnancy — lying flat on the stomach is uncomfortable.

Common Mistakes to Avoid

Even with the right technique, small errors can reduce pleasure or increase injury risk. Here are the most common mistakes couples make with the Flatiron position:

Thrusting instead of grinding

The flatiron is designed for smooth, grinding motions. Piston-like thrusting creates a different sensation that misses the point of this position's full-contact, grinding pleasure.

Restricting the receiving partner's breathing

The prone position with a partner on top can restrict breathing. Always check that the receiving partner can breathe comfortably and support your weight on your forearms.

Not elevating the hips

Without a pillow under the hips, the angle may not reach the G-spot effectively. The slight hip elevation is essential for the optimal internal stimulation angle.

Ignoring clitoral access

The clitoris (rated 2/5 without help) is accessible with hands from this position. Couples who forget manual stimulation miss adding another layer of pleasure.

Variations to Try

Once you've mastered the basic Flatiron, these variations can add new sensations and keep things exciting:

1

Add a Pillow

Place a pillow under the receiving partner's hips to change the angle of penetration and enhance stimulation.

2

Incorporate Manual Stimulation

Use hands to add clitoral or other external stimulation during the position for enhanced pleasure.

3

Slow Down the Pace

Switch from thrusting to grinding for a more intimate, sensation-focused experience.

4

Try Different Surfaces

Move from the bed to a couch, standing, or against a wall for different angles and experiences.
