this happens to a lot of guys with age. what you want to use is a penis health creme called man1 man oil. it contains the amino acid acetyl l carnitine which repairs nerve endings and restores penile sensitivity. it is safe and works great. google it and see for yourself. hope this helps and good luck!
why do i now have a lack of sensitivity in my penis. it isn't numb but takes a longer time to achieve orgasm? . i don't have difficulty getting an erection. i have plenty of energy throughout the day and t tests ok. i haven't taken medications for 4-6 months. (celebrex percocet tramadol effexor). i currently take 2000iu of vitamin d daily. vaginal intercourse works fine but oral sensation (lack of) is what seems unexplainable to me. . over the last 2. 5 years i have had a few cortizone injections in my shoulder and knee. but no major injury to my back.
