I started needing a shaving around 15 or so, but I didn't want to shave, I refused to since I knew that when I started it'd become eventually a necessity that I'd have to do over and over, and I refused to accept that. So I stuck 3 years with a beard that I hated, just because I refused to shave.
Then I finally gave up and started shaving, first once in a week, then 3 times a week, now I do it every other day....it sucks but it's a necessity, unless you like yourself with a beard, something I hate
