Masturbation is more intense stimulation than sex (after the first few times). Intercourse usually lasts longer once you get the hang of it. Masturbation is not damaging your health or future sexual prowess. For healthy diet: http://www.choosemyplate.gov/., exercise 30 minutes/day, drink enough water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs.
