lump/flap of skin just inside vagina?

So i had a baby in 2009 and had an episiotomy so i dont know if what ive JUST found is the flap of skin from that but idk youd think id have noticed it by now, right? I was just poking around down there, bored.. lol and just inside my vagina there was a fleshy lump the size of maybe a pea. I asked my husband to look and he said 'it looks like a flap of skin' and thats all he said. WTF could it be?
