yes I had the exact same thing up until a few years ago. i was able to use tampons but always had a very hard time getting them out. i wasnt even aware that it wasnt normal until i was 17. i tried doing research on it but didnt find much.
im not sure id recommend doing what i did, but one day i decided to take care of it myself. i found a pair of surgical scissors and sterilized them, and cut it. it was pretty thick and it bled alot, and took a long time to heal. i wound up having to tell my mother and she made me go to the gyno, who was actually impressed with my work! lol. he confirmed that yes it was a septated hymen. took a few weeks but it healed up fine.
theres no way youre gonna be able to stretch it out- it needs to be cut. so either do it urself very carefully or let the gyno take care of it

I actually did cut it myself... i was a bit embarrassed to say so. so u healed up nicely?
that's my main concern...
i'm afraid of an infection.

yeah it healed up.it doesnt look totally normal but then again what is normal.
were u sterile about it? if so keep the area clean and let it heal. but if ur concerned about it u should check with the gyno to be sure.
nothign to be embarrassed about. theyve seen much worse im sure.

I have this too! My gyno actually thought I had two vaginas. She asked if i wanted to have it cut and i was scared at the time but now i really want it gone. When i put in tampons, they get stuck behind the thick band of skin.

I do have a question though, did it ever make you itch when it tore a little or did it look like a pink sponge at the top ever? I was freaking out before trying to look at what it was.

thank you!
