Should I see the obgyn?

FYI: TMI ALERT AHEAD BUT WE’RE ALL GIRLS RIGHT AND I NEED SOME ANSWERS

Not to long ago I noticed this grayish/opaque substance around the inner lips of my vagina. It’s not a liquid substance, it has the same texture and look of when skin peels or like when you rub dirt and it kinda rolls up. I didn’t think to much of it but since I noticed this is a reoccurring thing. I was thinking maybe it’s because I might be having too much sex and maybe my vagina is irritated or dry and its peeling if that’s even possible? Has anyone experienced something like this? Should I be worried it’s something serious? I need answers! It doesn’t itch so I know it’s not a yeast infection. But I’d appreciate any type of advice or some ideas of what it could be.
