Aging
It could be worse. By age 30 my chest hair was turning grey. By age 35 my pubic hair was turning grey and I started using different hair dye combos with poor results. By age 40 I was shaving almost all and by age 45 I was shaving all of it off from my neck down to my knees.
Having the right blade does make a giant difference. A 3 to 5 blade razor (depending on your hair) works best. The 'throw away' types usually tear the skin and cause bumps. Using a simple pre-shave lube such as liquid shampoo or hand lotion worked well but not regular shave creams or foams.
Now, after many years of shaving, I just do it as part of my daily routine before I step into the shower or even skip a day or two...And now I don't like the feel of the hair, I do love the feel of the smooth skin.
