Hi Aunt Vadge!
A few days ago, Saturday actually, my boyfriend and I were having sex, and he drew back too far, did a hit and miss, and stabbed me with his penis on the inner lip of my vagina, right where the crease is.
Here we are Thursday and it kind of hurts.
There’s no blood and never was, but there’s a pretty good cut/split where he got me. This morning I started to apply Neosporin [antibiotic ointment].
- Is there anything else to do?
- How could a penis cut me?
- Or was it just from rough sex?
- And will it heal?
I’m scared hahaha!
Sincerely,
Scared
Dear Scared,
It will heal – these little splits almost always do. What’s happened is a common sex injury: a small cut in the delicate skin just inside the labia, from his penis drawing back and pushing in at an angle your skin wasn’t ready for. Five days of soreness is normal for a fresh graze there. Keep it clean with plain warm water in the shower, try not to touch it, and don’t use your vagina for anything in the meantime – no sex, no fingering, no masturbation, no dry humping – so it can knit back together.
In our clinic, sex injuries like this – a little split where the skin got tugged the wrong way – are familiar to us, and the vulva heals up well with rest and no re-injury.
On the Neosporin: you probably don’t need it. Antibiotic ointment around the vulva can knock back the protective bacteria that keep you healthy, so for a small clean cut, plain water and air are usually plenty. If it starts looking infected rather than just healing – spreading redness, pus, increasing pain – get it checked rather than reaching for more ointment.
How can a penis cut you? It doesn’t have sharp edges, of course, but it’s firm and there’s real force behind it. A hard thrust in the wrong direction can drag the delicate vulval skin further than it’s built to stretch and split one of the little joins around the labia or vaginal entrance. Add a moment where things weren’t quite wet or open enough, and the skin tears. Sex injuries are very common – men manage to hurt themselves too – and they happen at every age, because we get carried away and then, oops. It’s a good excuse for the two of you to talk about angles and going a little more carefully.
You can read more on looking after it on our vaginal fissures page and our guide to cuts and tears from fingering and rough sex. A dab of Delicate Cuts Cream can help a genuine cut like this settle.
A few things mean ‘get it looked at’ rather than wait:
- bleeding that’s heavy or keeps returning
- a deep or gaping split
- pain or swelling that’s getting worse
- pus, spreading redness, heat or a fever
- trouble or pain weeing, or it’s still not healed after a couple of weeks
Otherwise, you’ll be fine. Rest it, be kind to it, and it’ll sort itself out.
Warmest regards,
Aunt Vadge
