What is this?!

Okay so tmi but I don't know where else to go.... I'm 16, me and my boyfriend have never had intercourse but we've done oral etc; he's never been with anyone else, he doesn't have any STDS or anything like that... 
But recently I've have an itchy and sometimes painful sensation on my vagina. So I decided to check it out... Lol... So I just like looked down there and I noticed around the edge of my vagina there are little white dots that look sorta like little pimples but they don't pop or anything like that... I'm worried and I'm too scared to go to the doctors... Anyone have any idea what this is?!
