Is it ok for a male to masturbate/orgasm more than once in one day?

It is perfectly fine to masturbate more than once a day. There would be no adverse effects. You may notice, however, that with subsequent times, it may take longer to reach orgasm, so don't worry if that's the case.

OK & hardly like to harm you. But once/day will then let you spend more time doing somthing more productive like having an exercise regime, reading, spending time at a hobby or keeping in touch friends!

Agree with Drs. K and M Masturbation is harmless. Have a healthy diet, exercise 30 minutes/day, drink plenty of water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs. For nutrition: http://www.choosemyplate.gov/. Get HPV vaccine.
