Interactive Sexual Anatomy Explorer
Learn the biology of sexual organs without shame or confusion. This sexual anatomy explorer shows how internal erectile networks function, traces nerve sensitivity pathways, and sets out the normal variation between bodies.
Explore sexual anatomy by region
Clitoral Glans & Hood (Prepuce)
Function & Role in Arousal
The visible tip of the clitoris, packed with over 10,000 sensory nerve endings. The hood protects the glans from overstimulation.
Natural Diversity & Variation
Glans size, exposure, and hood prominence vary widely. Both retracted and prominent hoods are completely normal.
Nerve Pathways & Sensitivity
Highest density of tactile and pleasure receptors in the human body; richly supplied by the dorsal nerve of the clitoris.
Health, Hygiene & Clinical Care Tip
Wash gently with plain warm water only; avoid harsh soaps under the hood to prevent irritation.
How to use the sexual anatomy explorer
Select a region to open its breakdown: what the structure is, what it does during arousal, and which parts are visible versus internal. Most people are surprised by how much of the anatomy sits below the surface — which is the point of an interactive view rather than a single labelled diagram.
What each region covers
The explorer covers the structures that come up most often in sexual health questions, and links through to the full Openlywell guide for each.
- Clitoris — the visible glans and the much larger internal body, crura and bulbs.
- Vulva — the external structures, and how they differ from the vagina.
- Penis — erectile tissue, the urethra, and how an erection actually happens.
- Prostate — location, function, and why it matters for both health and sensation.
- Pelvic floor — the muscle layer underlying continence, orgasm and pelvic pain.
Normal variation is the rule, not the exception
Size, colour, symmetry and sensitivity vary widely between people, and none of that variation is a defect. What is worth attention is change: a new lump, a sore that does not heal, sudden pain, or a loss of sensation. Those are reasons to be seen, and they are not answered by comparing yourself to a diagram.
