Need help please...just worried some.?

Ok last night after i shaved and all i looked at my vagaina..and saw like a small white head near my vaginal opening and all. This is my first time i had one because i never seen it there before. Well I had white heads before and well they were in place i could pop and all. And this was all from shaving. Now I'm wondering if it's because i didn't use anything to shave the area? I used those bikini area shavers. And I know I got no STD I'm still a virgin and never had oral sex or any kind! Idk why but i want to pop it or something, but i mean it's in a spot where i'm afraid to. And it's small one and i can feel it popping out of their like a pimple does..Help?
