Dry white patch at the vaginal opening: what is it?

Hi Aunt Vadge,

I’ve noticed a dry, rough, white patch at the opening of my vagina. It’s not on the inside, and it doesn’t hurt or itch, but it’s not going away. My boyfriend and I have sex a lot – almost every night – and I don’t know if that’s causing it. I know I don’t have any STIs because I was checked recently, and my boyfriend lost his virginity to me. I’m worried – what’s the problem?

Thanks so much,
Worried

Dear Worried,

Having sex every day – particularly with condoms – can be a cause of irritation, and that irritation often looks like dry, rough skin, a sort of contact dermatitis. It happens because the skin’s normal barrier function has been interrupted, which very regular friction like sex can easily do. Because you keep contributing to the irritation, it sticks around.

Give it a proper break

What I’d suggest is taking five days off penetrative sex. I know that’s hard if you like it every day, but think of it as a chance to learn how to pleasure each other without penetration or touching the vaginal opening, particularly where the patch is. It needs a complete break from being touched – that includes wiping delicately after you pee.

If the patch is on the dry part of your inner or outer labia, apply a small amount of petroleum jelly (like Vaseline) to protect the area and trap moisture in the skin. It acts as a barrier, keeping the skin hydrated and protected – you don’t need much, just a soft, protective layer against further irritation, which also works as a gentle lubricant for your underwear and for wiping.

When you wash, be really gentle and skip any skin-stripping soaps – you know the ones, because your skin sort of squeaks afterwards. Use only a tiny amount, or none at all on that area, rinsing with warm (not hot) water, since hot water strips your natural protective oils faster. You want to keep those oils around to get your skin back to normal.

Your body isn’t magic, and just because you can physically have sex as often as you like doesn’t mean it comes without consequences for your delicate tissues. Having a lot of sex comes with a greater risk of little cuts, abrasions and irritations, so knowing how that damage happens and how to prevent it is key to a happy, healthy vagina. Also check any lube or condoms you use and make sure they’re hypoallergenic – no flavours, colours or irritants – as those could be contributing. If you’re not using lube, it’s a good time (after your five days) to start.

If it doesn’t clear with a rest

Vaginal tissue usually heals quickly, so you’ll know within about five days whether friction was the culprit. If it clears, wait until it’s completely healed – really completely – before you start having sex again, and pay attention to being well-lubricated every single time, avoiding any pulling on dry labia.

If the patch doesn’t budge after a good break, that’s worth having looked at, since a persistent white patch can occasionally be a skin condition such as lichen sclerosus rather than simple friction – and that’s very treatable once it’s identified. Write back and we’ll talk some more.

Warmest regards,
Aunt Vadge
