Is my vagina too short? Why a finger-test misleads

Hi Aunt Vadge,

I’m worried my vagina is too short. If I put my index finger in I can easily touch my cervix, even when I’m turned on. I’ve read the vagina stretches during sex to accommodate things, but I wanted to check. I haven’t had sex, but the guy I’m sort of seeing has a 7-inch penis and I’m a little worried about that.

Thanks!

Hi Too Short,

Take a breath, because you’re very likely not too short — you’ve just measured at the wrong moment. When you become fully aroused, your vagina lengthens and balloons (it’s called ‘tenting’) and your uterus and cervix lift up and out of the way.

A finger-test, even when you feel a bit turned on, almost never captures your fully-aroused depth, so ‘I can touch my cervix easily’ is a very normal reading that doesn’t mean what it seems.

A 7-inch penis is far more accommodate-able than you fear, once you’re properly warmed up — the trick is real arousal time before anything goes in, and positions where you control the depth, with you on top being ideal.

If he ever bumps your cervix it’ll feel like a deep, bruisey ache; that’s your cue to change angle or go shallower, not a sign you’re broken.

Before any partner, it’s worth exploring solo so you know what feels good and how much you can take. Start small and gentle, and don’t be surprised if you prefer girth over length — plenty of people do.

Your cervix also moves through your cycle, sitting higher and softer around ovulation, so that’s often the comfiest time, which is one more reason charting your cycle is useful.

And even if penetration is never your main event, that’s no loss at all: the clitoris is where most pleasure lives anyway, and oral, hands and toys are a whole rich world — couples who can’t rely on deep penetration often become far more imaginative lovers.

The only time to get checked is if penetration turns out to be consistently painful or simply impossible even when you’re relaxed and aroused, in which case a sexual-health clinic can rule out a vaginal septum or other structural variation — uncommon, but good to know about (there’s even a recognised thing where the vagina feels shorter than it measures).

Most likely, though, you’ll find you’re perfectly, normally built, just needing arousal and a bit of know-how.

Warmest regards,
Aunt Vadge
