Vaginismus is most commonly recognised through what happens during penetration or when penetration is attempted. Understanding where the sensation occurs, and why, is often the first step in making sense of the experience.
Most commonly, the sensation is felt in one or more of these areas:
The most common site. Sensations here are often described as burning, stinging, tearing, or the feeling of hitting a wall. For some people, discomfort begins before penetration happens. With touch alone, or even in anticipation of it.
People describe it as skin that feels grazed or sunburnt, or a sharp localised sting rather than a dull ache.
The sensation here often feels just beneath the surface rather than deep inside. This is the zone where involuntary pelvic floor muscle contraction most commonly occurs, and the intensity can be significant even with a finger, tampon, or dilator.
Some people experience burning around the opening rather than directly inside it. This can extend to the perineum the tissue between the vaginal opening and the anus.
Clinically, the burning sensation is thought to result from a combination of factors: protective muscle tightening that reduces blood flow and increases pressure on sensitive tissue, heightened nerve sensitivity at the vaginal entrance, and anticipatory threat responses that amplify sensory signals.
This is why people sometimes describe a sensation of skin being on fire, even when the tissue appears completely healthy on examination.
Not all burning at the vaginal opening is vaginismus. Similar sensations can occur with provoked vestibulodynia, infections or inflammatory conditions, and hormonal tissue changes.
In vaginismus specifically, the burning is usually situational it appears with penetration or attempted penetration and is linked with involuntary muscle guarding.
If you’re unsure what you’re experiencing, a GP, gynaecologist, or pelvic floor physiotherapist can help clarify the cause.
