This isn't fully about sexual health, but it is regarding the health of one of my sexual organs, so I hope this is the right board.
It's a tad embarrassing to admit, but I was cleaning myself a few hours ago (after using the toilet) and I had a shiver (idk how to best describe it but they're normal for me) and lurched forward a bit. Usually this wouldn't be interesting, except due to where my hand was (and the fact I rarely clip my nails) I think I accidentally cut myself inside my vagina/vulva (idk specifically where I couldn't tell from the outside but I don't think it was super deep or anything).
Right now, it doesn't really hurt at all, but when it first happened there was quite a bit of bright red blood (I put a period pad on, but it's not collected any since, suggesting the blood was from a cut rather than a period and also that the wound isn't bleeding)
However, I had to pee again a bit later (I drink a lot of soda, okay??? >.>), and whilst the urine didn't cause any major irritation and whilst I was mostly able to clean myself by being really careful, at one point I experimentally tried to wipe normally and it hurt (not like a dramatically toppling over, oh no I'm gonna die/my genitals are gonna fall off, just an "owwww I shouldn't have done that ow"). Also I can feel a mild injury if I sit in a particular way.
What I'm mainly asking is: is there anything I can specifically do to help it heal fast/avoid infection because I've heard this area is really easy to infect and I feel a cut (especially one that comes into contact with urine) is going to be really susceptible to infection and I don't really like messing with that area of my body (also I feel like sticking disinfectant there wouldn't be very good)
On a slightly more amusing note I now understand a joke I once heard about why lesbians can't wear long nail extensions.
