Re: vaginal cut, help!
I'd quit putting antibacterial ointment on it.
That may be preventing healing (by keeping it moist and greasy).
If I were you I'd try witch hazel instead.
It's a very mild astringent, safe for use on the genitals.
After the birth of my first child, I had some stitches in my vagina, and the doctor recommended witch hazel compresses. It worked really well, dried the area out and let it heal.
My husband uses witch hazel on his hemorrhoids. It seriously is very mild. It won't hurt you at all.
But since you're not having any luck with this ointment, you might go ahead and try this; use it to dry the area out, and healing may ensue.
Best of luck.
