Weird hard lump on my ?

I'm really sorry for asking, but I've had a tiny yellow-gray bump on the bottom of my for about a month. I decided that it was a zit, so when I tried to get rid of it, a gelatin-like substance popped out (gross, i know. so sorry!). The jelly thing was solid, and there was no liquid or anything. When I looked at where it formerly was located, I couldn't help but notice that there was a hole in my ! Yes, a hole. It's like 1/16 of an inch...maybe even smaller. Can someone tell me what it is? Sorry again for all of the gory details:( Thanks<3
