I am 17 years old and have never had sex or done anything sexual.. but masterbate. Ive noticed a bump on my labium majus about the size of half a grape (maybe a bit smaller).. right before it started forming I had popped a little pimple right next to wear this bump is and I had thought it was a pimple too but it doesnt pop bc theres no hole for it to be released.. It doesnt hurt unless I apply pressure to it and when I was showering I let hot water run on it for a min or so and it went down a bit.. Im just a bit worried and want to know what it is and how can I make it go away? I havent shaved or anything for a long time so I dont think its an ingrown hair.. Oh and a couple days after it started to appear I started my period and still currently on my period and the bumps still there. Been there for a week maybe? pls reply and let me know what you think.
