Can penis nerve damage cause premature ejaculation? because when i masturbate i dont feel any anything really anymore and i cant last long anymore?

No it is not from nerve damage. It can be caused by many things and is a symptom. You should see a Urologist or a sex thrapist

Give it some rest. You may be overdoing the masturbation. Try to limit it once a week. 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/safer-sex
