Des marques en dehors du vagin. Cela ressemble-t-il à une irritation causée par un fil de tampon ou à des rapports sexuels ?

I'm really not sure if these sores were from tampon irritation and scratching or from sex? Has anyone had something like this before?

cant say ive ever had the tampon string do that. do you have long nails? maybe cut yourself whilst changing tampons or scratching. id see a doctor in any case
