I had a cyst taken out of the top my head 6 days ago and i have stitches can i masturbate?

I don't see where the head wound would have any influence of any of your usual activities other than those that involve it directly. In other words, don't play soccer & head butt the ball.

You may. Masturbation will not interfere with the healing process of the incision on your head. 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. Get HPV vaccine. Wish you good health! Safe sex: https://www.hopkinsmedicine.org/health/wellness-and-prevention/
