Ouch! That must have really hurt to have caused such lasting damage. It takes a lot of effort to permanently stretch your skin like that. My guess is that your labia were always going to be having lots of folds, thanks to your genes and the cocktail of hormones that got you through puberty.
The dots sound like Fordyce spots, which are oily glands (sebaceous glands). 80% of people have them regardless of gender. Some more than others. They are usually found with a hair follicle. You can get them on the skin around your vulva, on your labia as well as in between the labia minora and majora, the clitoral hood, as well as the lips of your mouth, and less frequently around the nostrils and under eyes.
Here’s what they can look like on a vulva.
They are not caused by an STD. They are benign and don’t need to be treated in any way. You shouldn’d squeeze them or try to get rid of them. If you are really concerned about their appearance then see a dermatologist.
