I'm 17 and I have noticed a hard lump/swelling inside the bottom of my labia majora close the the hole of the vagina and it a sort of sac that I can touch and move slightly but it hurts I didn't hurt to sit down at first but now it does but not terribly... Every cyst I have seen doesn't seem to look like what I have to be honest it just looks a little swollen it's not noticeable but you can feel it under the skin. I seem to have developed this mysterious thing after me and my partner had sex about two weeks ago (we have sex quite often) could that be the cause? I read up That shaving there could have effected it but honestly I'm confused someone please give me some advice ASAP. Lots of thanks
