Concern in Vagina

daisy

So I have been wanting to go to a gynecologist for this concern, but I’m below age to go without consent so I told my mom if I can go and she said she has to ask my doctor but I can’t go now because they are only taking appointments at doctors if you have emergency due to Covid. I see everyone who has a vagina has just a hole to the vaginal opening but I have a like lump/area of skin that’s kinda big and it’s been there a long time and I don’t know what’s wrong with me. I can stick a tampon in there fine but I’m concerned about this random piece of skin on my vaginal opening. It’s been there my whole life. Is this normal? Help!!!
