Hi, I'm 14 Years Old And I'm A Virgin. Not

Hi, I'm 14 years old and I'm a virgin. Not too long ago, I noticed a small lump on my clitoral hood. It was the size of a pea, it was skin colored. It wasn't abnormal, there wasn't a head, it wasn't sore and I had no strange symptoms.
I popped it a few times, which it would come back after until the final time when I put ointment on it and it went away.

I have it again and this time, it's the same thing. It's under my skin, I feel something popping under. I'm putting ointment on it and starting to soak it in hot water. When it pops, it becomes swollen.

I don't want to tell my mom or see a doctor, that is the last thing and I don't want to unless it's absolutely life threatening.

What is it? Is it life threatening? What can I do to make it go away?

I do masterbate in that area, could it be because of that?

Should I leave it alone? It doesn't seem to be growing. I just hope it goes away. I don't want to see a doctor or tell my mom, I just want to know if it's life threatening or not. I'm really scared.
