On December 18th, my boyfriend and I were performing sexual actions. He and I are virgins and all we did was oral sex, and he also fingered me. This is not the first time that any oral sex took place; however, this was the first time that there was any fingering. After that day it has felt uncomfortable to sit, walk, or even urinate. Yesterday I was extremely concerned and looked to see why it felt so uncomfortable and I saw bumps on my vagina and the left labia (I believe this is the right word) is slightly swollen. I am 18 and my boyfriend is 19. My parents have yet to know about him, so I don't know how I will get to an actual gynecologist. I am very scared and I just want some answers. Can you help me please?

I have put Vaseline on the irritated area and I have washed the area as well. And last night I slept with the Vaseline on and no underwear to see if the underwear was adding to irritation.
