The Discovery of the Hidden Treasure: face-down rear entry
The Discovery of the Hidden Treasure is a rear-entry position with the receiving partner lying face down. She keeps her pelvis and legs on the bed, legs stretched out and together, and raises her upper body on straight arms, like a yoga cobra. Her partner kneels upright astride her thighs and sets the pace. It allows vaginal or anal penetration of medium depth and asks for moderate effort, mostly from her lower back and wrists.

Anatomy and biomechanics
The receiving partner lies face down with her pelvis, thighs and legs resting on the bed, legs stretched back and close together. She raises her chest by straightening her arms, hands flat on the bed under her shoulders, and lifts her head, which arches her lower back. The penetrating partner faces the same way and kneels upright astride her thighs, with his knees on either side of her legs and his hands on her hips and buttocks. Penetration can be vaginal or anal and is usually of medium depth; with her legs together, some people notice a tighter sensation. He sets the rhythm, while she can adjust the angle by arching more or less. There is no eye contact or kissing, and body contact is limited to the pelvis, the thighs and his hands.
Why this position works
Many people like this position because it is simple to get into from lying face down and the receiving partner can rest her pelvis on the bed. With her legs together, some people find the sensation tighter, and by arching more or less she can change the angle without moving much. The kneeling partner has a clear view and full control of the rhythm, which some couples enjoy. Her pelvis rests on the bed, so she can also press against a cushion or slip a hand underneath. Sensations vary from person to person.
Variations of this position
Variation 1: on the forearms
She lowers her chest and rests on her forearms instead of straight arms, like the sphinx pose.
Resting on the forearms reduces the arch in her lower back and takes the load off her wrists, so she can stay longer. Her pelvis tilts slightly, which changes the angle of entry. He stays kneeling astride her thighs and sets the pace.
- From the base position, she bends her elbows and lowers her chest until her forearms rest flat on the bed.
- She keeps her legs stretched out and together, with her pelvis on the bed.
- He adjusts his position on his knees to line up his hips with hers.
- Start again slowly and agree on the depth.
Variation 2: with a cushion under the pelvis
A firm cushion under her hips raises her pelvis a little.
The cushion lifts her pelvis, so she does not need to arch her back as much to make entry easy, and the angle of penetration changes. It also gives her something to press against, which some people find pleasant. Everything else stays the same.
- Place a firm cushion or folded pillow where her hips will rest.
- She lies face down over it and raises her upper body on her arms or forearms.
- He kneels astride her thighs and finds the height that suits both of you.
- Move the cushion slightly up or down if the angle is uncomfortable.
Variation 3: with her legs apart
She opens her legs and he kneels between them instead of astride her thighs.
With her legs apart, entry is easier and he can come closer, so penetration may feel deeper and less tight than with the legs together. He kneels between her thighs, hands on her hips, and her upper body stays raised on her arms.
- From the base position, he moves his knees inward while she slides her legs apart.
- He kneels between her thighs, upright, with his hands on her hips.
- She keeps her pelvis on the bed and her upper body raised.
- Adjust the depth gradually, as it may feel different from the legs-together version.
✓ Tips
- Use lubricant; for anal sex it is essential, along with a condom, and use a fresh condom before switching from anal to vaginal sex.
- If her lower back or wrists get tired, she can lower herself onto her forearms or put a cushion under her pelvis to arch less.
- The kneeling partner should keep his weight on his own knees and not sit on her thighs.
- Avoid hard, fast thrusts from above: if the penis slips out, guide it back in by hand, because a misdirected thrust can injure it.
- Go in gradually, agree on a signal to slow down or stop, and stop if there is any pain.

Frequently asked questions
Is this position suitable for beginners?
Yes, it is fairly easy to get into and needs little balance. The main effort is keeping the upper body raised, so take breaks or rest on the forearms if the lower back or wrists get tired.
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. Use a fresh condom before switching from anal to vaginal sex.
What if her lower back hurts?
Arching too much can strain the lower back. Lower onto the forearms, put a cushion under the pelvis or keep the upper body lower; if the pain continues, change position.
Is clitoral stimulation possible?
Her pelvis rests on the bed, so she can press against a cushion, slip a hand underneath or use a small toy. Not everyone finds it comfortable, so try what works for you.
Safety and evidence
This section summarizes anatomical and clinical evidence relevant to this position. The sources provide context; they do not show that a specific position guarantees pleasure, orgasm or a particular type of stimulation.
G-spot: what the evidence says
The “G-spot” is a widely used term for a sensitive area of the anterior vaginal wall. Scientific literature has not demonstrated a discrete anatomical structure with an agreed location, size and nature; sensitivity and response can vary from person to person.
Anatomical variability
Vaginal shape, axis and dimensions vary considerably from person to person. As a result, depth and comfort may differ even when using the same position.
Lubrication and comfort
When there is dryness, friction or discomfort, a suitable lubricant may make sexual activity easier and improve comfort. Its use is not universally necessary.
Anal sex: care and prevention
The anus does not lubricate itself and its lining is thin. Plenty of lubricant, a condom, going slowly and being able to stop at any moment make it more comfortable and lower the risk of injury and infection.
Penile fracture: prevention and warning signs
It is uncommon, but it can happen when the erect penis bends suddenly, often after slipping out and hitting the partner’s pubic bone or perineum. Moving with control and slowing down if the penis slips out helps prevent it.
Clitoral stimulation and orgasm
For many women, the most reliable route to orgasm is clitoral stimulation, direct or indirect. A position that leaves hands free or lets the clitoris be rubbed makes it easier to add during penetration.
STI protection: condoms and dental dams
A condom, put on from the start and used throughout, is the most effective way to reduce sexually transmitted infections during penetration. For oral sex, a condom or a dental dam lowers the risk.
