You're right about one thing--if you haven't had sex, you don't have an STD. The only way pimples of the sort you describe could get a scab on them is if you pick at them. I have little doubt that you're doing that because you are worried about what they aren and are worried that sex will be too painful to tolerate. It won't. These pimples are almost certainly the normal cysts I have described to so many other questioners. You cannot remove them. Please don't try. They're part of you, and they belong there.
If you're as worried as all that, you need to consider medical and/or psychological counseling. I know the prospect embarrasses you, but you deserve to overcome your anxiety and have too do what ut takes so you can get on with things.
Good luck.
