vagina question

So the area directly around my vagina is usually puffier and just checking now( after shower) it seems to be darker than usual and dare I say, wrinkly? Again this is not the inner or outer labia I'm talking about. It just looks idk, savvier? And darker than usual. I haven't had sex and I'm only 16. Is it from masturbation , will it go back to normal?? As well as my lips themselves they seem darker as well
