Please Help! What is this?

What is this? Ive noticed this bump on the skin around my vagina for about a year. Its never been painful, but it does occasionally get bigger, but then it always shrinks back down. It has never looked like this, however. It doesn’t hurt, but it is a little tender what touch it. I shaved recently, so It could be an ingrown hair, but it just doesn’t go away completely. It’s a pretty big bump.

this definitely looks like an ingrown hair, you can see the trapped hair right under the skin
