Aunt Vadge,
I have a question about labial tears. My wife recently mentioned she’d had a labial tear one night when things were getting romantic. That puzzled me, because my understanding is that labial tears usually come from sex or childbirth – and we hadn’t had sex for at least a week.
When I pressed her, she said it might have happened taking off her underwear, or scratching in the car, or on the bidet – she wasn’t sure exactly when. She showed me the tear; it was about a 1 cm split. She also said it’s happened before, but couldn’t recall when.
We’ve been together over eight years and this is the first I’ve heard of it. How plausible is her story? Some medical professionals I asked (not gynaecologists) thought it unlikely. I’ve had recent suspicions about infidelity, so my mind went there. I’d value a professional opinion.
Sincerely,Concerned
Dear Concerned,
Your actual question first, plainly: a labial tear is not evidence of infidelity. It cannot tell you who has or hasn’t touched her. So whatever you decide to do about your worries, please don’t let this tear carry that weight, because it simply can’t.
The idea that labial tears usually come from sex is a myth.
The inner labia are delicate skin – not unlike your lips – and small splits and fissures are common from all kinds of everyday things: friction from tight clothing or pulling underwear off quickly, a sharp nail or hangnail, vigorous wiping or a bidet, scratching (especially with a skin condition like eczema or a strong itch from yeast), nutrient deficiencies that make tissue fragile and slow to heal (protein, zinc), hormonal changes sometimes with no other symptoms, and skin conditions like lichen sclerosus, scleroderma or dermatitis.
Every cause on that list is non-sexual, and her explanations – underwear, scratching, the bidet – all fit comfortably. The professionals who doubted her weren’t vulvovaginal specialists, and in our experience a small split someone can’t time precisely, that’s happened before, is completely ordinary.
One detail to correct, since it’s clearly been on your mind: the labia are rich in nerve endings. But like a split lip a small tear can be barely noticeable until you knock it, so ‘I didn’t catch the exact moment’ is very believable – people find little injuries on themselves all the time without remembering how.
And if the damage were around the vaginal entrance rather than on one lip, that would be the more sex-associated pattern, which isn’t what she’s describing.
If she’s getting these splits repeatedly, that’s worth looking into – not for relationship reasons, but because recurrent labial fissures can point to an underlying skin, hormonal or nutritional issue – so she could see a doctor to have it examined. And our guide on treating a simple vulvar tear may help in the meantime. (One small kindness: she mentioned feeling her labia are ‘massive’.
They’re almost certainly perfectly normal, since inner labia vary enormously, and she may already feel self-conscious about that area, which is worth holding gently.)
The part that actually matters: your feelings are valid, and you clearly care – you’ve done your homework.
But I’d gently put it to you that the tear has become a stand-in for a bigger fear, and sometimes ‘you’re cheating on me’ is what comes out when the real feeling is ‘I’m scared of losing you.’ There’s a lot that happens in our bodies we never mention, not for any sinister reason but because there was never a reason to – and if I knew a small injury might get me accused of an affair after eight years, I’d have kept it to myself too.
So my strong advice is: don’t make the tear the conversation, because it can’t bear that weight and may be exactly what she says it is, with no way to prove otherwise.
Lead instead with how you feel, openly and without accusation – and if the trust issue is bigger than this one moment, that’s worth real support, because couples therapy can really help rebuild it. Whatever’s going on between you, you’ll get much further with an open heart than a cross-examination.
I hope you both heal, the tear and everything around it.
Warm regards,
Aunt Vadge
