Septate hymen! Help!

Juliana • 🌸⚡️🍑
I tried wearing a tampon for the first time and found out I have a septate hymen because taking out was extremely difficult and painful 😖  (there's a little string in the opening of the vagina and the tampon got stuck once it was full). Days after, I went to the gyn and he told me he'd rather not doing anything about it until I have sex for the first time, but of course it is up to me. I could have surgery and get rid of it. I don't know what to do! It scares me how painful sex could be with that string in the middle. Will it break? Help please!
