When genital lies dormant, do you still get sores?

I'm really curious because I have never had before, and I have a few extremely small bumps (almost like whiteheads) in upper area of my . I have seen pics of what looks like and the bumps are nearly microscopic compared to those. I also don't have any pain. I don't even see how I could possibly contract it.I don't think I have but I just want to know what you think. I've also heard of sebum glands (like oil glands on your face, only bigger) that produce a special kind of waxy substance called smegma - which protects the area from germs, friction, etc. Sometimes they are bigger than other times, and they fluctuate in size....some will look almost like a whitehead. Are these just a few sebum glands??
