i have weird red bumps/sores around my pubic area

so i'm 14, and i don't really shave my pubes that often. i just don't feel the need to because i'm not sexually active or anything. so the other weekend i decided to shave because i was going to my boyfriends house and we might get a little frisky (we didn't). that night i was kinda itchy down there, but i thought that was normal. then the next couple of days the skin between the bottom of my vag and my as****e was really sore. i thought this was weird so i put some type of ointment on it. then i started getting these weird pimple looking bumps on my inner thighs. some of them almost look a spider bite if you've seen one. now i have a few on my legs and one on my arm and a bunch on my ass/inner thighs. and i have a bunch of dry looking red bumps all over my lower ass and behind my vagina. i don't know whats going on and i'm way to embarrassed to ask my mom! please i'm really worried and need to know if i should see a doctor.
