I need abit of help? Women only please?

I think there might be something wrong with my birth hole:( I'm 16 and virgin so I looked down there and what I saw was a round opening which I'm guessing is the holes entrance and then a layer of skin which I'm guessing again to be the hymen but the thing is the layer of skin covered the entrance. Is this normal because I read up that if your hole is wholly covered you have to get this removed surgically although this is a one in 2000 case is it possible I can be this 1 person? Could it just be my hymen sitting there normally or is this abnormal? I'm freaking out! So when I looked at it looks like my future husband would have to push through it to get inside to be exact.. Argh this is worrying:(
