Are small bumps on my ball sack normal! and what about vines on an erect penis? thanks for the answers

Sometimes: depends exactly what they look like. advise to see dermatologist for evaluation. veins on erect penis quite often are normal, but should see doc to be reassured.

Bumps on scrotum: You MAY have some small cysts called fordyce spots on your scrotum. Please see your doctor. Peace and good health.

See below: Visible veins on the penis are normal. If the "bump" are stable and not growing in size, let those be. Those are likely prominent hair follicles. Have a healthy diet, exercise, drink plenty of water, have safe sex, and get HPV vaccine. Wish you good health! Nutrition: http://www.choosemyplate.gov/.
