White bumps on testicles and surrounding areas

I've got these white bumps on my testicles and surrounding areas. Some of them are little, the little ones pop like zits and there's a white hardish puss... it has the look/consistancy of what you find in between an oreo cookie. If it was just these I would assume I had zits on my balls and not think much of it, but there are also bigger ones that don't pop like zits, they're actually pretty deep. I took a knife to one of them a few months ago (I've had these for about a year and a half now, I'm a virgin so I never thought about it being an STD, but I recently found out that you can have STDs w/out ever having sex) and when I got down into it I pulled the white thing out, and it was the same consistancy of what you'd find in an oreo cookie, maybe a little thicker. I pop the little ones but they always come back, and the big ones I'd have to take a knife to.
They don't itch, they don't burn, they don't hurt at all, they're just there. However I don't have insurance and money to go to a doctor is tight, but I've been turning down dates with girls for a while now for fear they'll lead to them wanting more which would lead to them seeing my junk which would lead to them refusing anything and telling everyone that I have some sort of STD. Anyways, i figure I have to go to the doctor anyways... but if there's a chance i can fix it with anything I can get over the counter it'd save me alot of worry. Any help would be much appreciated
