If you have had sexual activity, it could be genital warts.
Hello. I agree you should get checked out and if you have had sexual activity, look into hpv. There are other lumps and bumps we ladies get too. Here's an article to look at which talks about that. https://www.healthline.com/health/womens-health/vaginal-lumps-bumps We have a bunch of glands in that area and if one gets clogged, a cyst can form. We can also get fordyce spots which are a build up in that area too. These both are normally harmless. I'd get them checked out.
