You get STDs from sexual contact. If you have not had any sexual contact, it's pretty unlikely that you would have an STD.
At any rate, I saw your pictures before they were removed, and you look normal to me. There are some bumps you can get that are not really supposed to be there (like genital warts), then there are others that are perfectly normal, not contagious, and nothing to worry about.
Your bumps look like the normal kind. The bumps around the head of your penis might be pearly penile papules. Your picture was not quite close up enough for me to say with certainty, but you could google pearly penile papules and see if that is what yours look like up close.
The bumps more around the base and shaft look normal too. The skin on the genitals often looks kind of like chicken skin or like goosebumps.
However, when in doubt, don't be afraid to show your doctor.
