So im 13 and like a year and a half ago I noticed that the opening to my vagina/inner labia was a weird grey-ish yellow color and had a weird texture. And it's was like a bold line on both sides. Like almost bumpy but not quite. It just has a way different texture then the rest of my inner labia. I've done my research and it's definitely not warts. Also it's not itchy and it doesn't hurt at all. It doesn't hurt when I put in a tampon or anything. I'm a virgin but have masturbated before. I'm really scared. Pls reply asap!
