Bumps on Penis ?

Hello, I'm in my late 30's and when I was 18 i was diagnosed with Genital Warts. In my early 20's a new doctor stated I don't have genital warts and the bumps were instead nevus or nevis ? Anyway, I now suddenly show new bumps on the back of my penis that do not look like anything from my past and it's near the head which I think is called the foreskin ? Its different. Please see images. Are these warts ? Cancer ? what ! HELP :(
