Is it normal to be wet down there? How the vulva and vagina stay moist

Yes. Feeling wet is normal: it's how a healthy vulva and vagina look after themselves. The two stay moist in different ways.

The vulva

The skin of the mons pubis and outer lips has oil (sebaceous) glands that keep it soft, and it can also sweat. The inner lips have no sweat glands but plenty of oil glands, which matters because they're often exposed.

Two sets of small glands add to this. Bartholin's glands are pea-sized and sit either side of the vaginal opening. They release a slippery fluid, mostly during arousal, which eases friction at the entrance. Occasionally one of these glands gets blocked and forms a soft lump called a Bartholin's cyst, which a GP can check. Skene's glands sit beside the urethra and keep the urethral opening moist. They may also play a part in arousal and squirting.

The vagina

The vagina has no glands of its own. Most of its moisture comes from fluid seeping through the vaginal wall from small blood vessels underneath, a process called transudation. More blood flow, from warmth, movement or arousal, means more fluid. Mucus from the cervix travels down and mixes with this fluid, along with small amounts from the womb and fallopian tubes. Cervical mucus changes through the menstrual cycle, becoming clear, stretchy and slippery, like raw egg white, around ovulation. This mix of fluids is what we call discharge.

What's normal?

Discharge varies from person to person and through the month. Normal discharge is clear or white, can be thin and watery or thicker and creamy, and has little or no smell. It's often heavier around ovulation, during pregnancy and when you're aroused, so feeling wetter all of a sudden is usually nothing to worry about. A change in colour, smell or texture, especially with itching or soreness, is worth getting checked.

What keeps it working

Oestrogen keeps the vaginal lining thick and stocked with glycogen, a type of sugar. Around the vulva, it keeps the lips full and the skin supple. Lactobacilli, the vagina's main friendly bacteria, feed on that glycogen and produce lactic acid. This keeps the vagina slightly acidic, which helps keep unwanted microbes out. Good blood flow supplies the fluid that seeps through the vaginal wall.

30-second summary

The vulva moisturises itself with oil, sweat and gland secretions. The vagina draws fluid through its walls and mixes it with cervical mucus to make discharge. Oestrogen, good circulation and a healthy microbiome keep it all working.
