Help! Do I have stds??

Ok so I’m a 15 year old virgin, and I never had any sort of sexual contact with anyone before, but I do masturbate . I just noticed this today and I’m worried. It doesn’t hurt in any way, it doesn’t itch, and it doesn’t make me uncomfortable. I feel like it’s because my vaginal discharge has gotten more, umm how do I say it..there’s much more to where it goes through my underwear. And I feel like it’s because I change my tampons out a lot since rn I’m on my period. But this never happened to me before, and I’m worried on what this is..help?

There are tiny bumps that are around my vagina lips, but they don’t look like warts or cysts, but they look like tiny white pimples around the top of my vag lips btw (also it won’t let me add pics so I’m describing it)

You can't have an STD from non-sexual contact, although you could end up with UTI if you use contaminated items. To attach pictures, do not chat from a cellphone as it wouldn't give you the option to attach. But if you are so worried, you might want to have a doctor check you out.

You don't have it. No worries
