What Causes Bumpy Fleshy Things In Vagina?

Height: 5"1 Weight: 7 stone 2. No medical history. Been on the pill and on the depo injection.Recently ive found bumpy fleshy things in my vagina. Like the vagina entrance. I think it's on my hymen but not sure. If I rub over my vagina intrance, or put my finger in a tiny bit and push sort of upwards.. Is it supposed to be bumpy and rugged? I also use tampons..
