Hi. Masturbating will not have caused this. If you are not yet sexually active it cannot be an STI. Do not pop these bumps. Doing so will spread bacteria under the skin leading to more spots, delayed healing time and possible secondary infection.
Bumps on the penis are unlikely to be acne. Acne commonly occurs on oil-rich areas of the skin such as face, chest and back. I am only an expert on acne so you may wish to repost this question in the Dermatology Forum.
Best Wishes.
