Okay, so for over a year or two, I've been getting these pimple like things on my Mons Pubis. I am 14 years old, not sexually active, and have changed my shaving razors multiple times. But, I also share my razor with my mother and older sister, both of which are sexually active. But, today, I was examining my vagina completely. When I came upon stretching my Labia minora or clitoris (Unsure of name, I looked up the parts online) and came upon about 3 or 4 white bumps. When I pinched them, they didn't puss, but completely came off. This hurt, but still took it off. I have a past of self harm by cutting, but I always washed the cuts and never used a dirty blade. At that, it was on my stomach. I'm unsure of the itching, due to the fact that I shave down there often. So, is this a possible STD or something of that sort?

~P.S. Sorry if this is posted in the wrong area, I'm new to this website.
