SOS!!! ITCHINESS NEAR COOCH

mom, i just turned 16 and ive never been to the gyno....okay so i lost my virginity around 3 weeks ago, but there's no chance of anything like that because we were both virgins...but anyways to the issue, my vag has been very itchy the last 3 days, to the point where it bothers me so much i could barely sleep at night...there's these pimple looking bumps surrounding it to, and im having white thick discharge...i thought it was a yeast infection???does anyone know what this might be, and how i can help to make it go away/relieve it...i put lavender oil on the bumps and it only made a little

difference...i put plain yogurt around it yesterday and it helped a lot...
