My peehole is on a bump that looks like a sponge. Is this normal?

Your peehole is on a bump?

Do you mean that there's a bump on your vagina, or a bump on your urethra? How is your vagina or urethra on a bump?

Time to see your doctor, the information you posted makes no sense.

Good luck.

I guess it depends on whether you are a boy or a girl.

I assumed the OP was a girl since this is posted in the women's health forum, but anything is possible. ;)
