I Have Been Getting Strange Bumps In My Pubic Area

I have been getting strange bumps in my pubic area for a couple months now and I'm really nervous because they didn't start until after I had unprotected sex the first one I ever got was a short time after the I had the sec and it was big and on the bottom of my left inner thigh it busted open since then I have gotten small bumps and big bumps on my public area, between side folds of my vagina and on my inner thigh they go away and come back in the same spots always they take forever to go away
