Weird question

So it's never been a problem before, but since everyone is so open and welcoming on this site: right above my vagina opening/ urethral opening I have a weird string of skin probably about half an inch maybe less long. It doesn't hurt, isn't causing any issues I just wanna know what it is. I can post a pic if it would help but just want to know if it's something to be concerned about. I've had it literally as long as I can remember.
