weird flesh like blockage in my vagina?

sorry if this is tmi but I need help figuring out if this is normal or not. today I felt down there and noticed that: In my vaginal opening I can't even see the actual opening, it's like a tissue that looks and feels like another set of labia almost, like a little tongue poking out of my vagina. It's really concerning to me. I can still fit a finger inside because the actual opening seems to be underneath it. I found a similar post on here and was just wondering if someone knew what was happening so I'd know to go to the GYN or not?! please help
