Hi Chris,
Well for me i've put 4 years or more because I've been going to nudist beaches since 2006 :D I first became really interested in being clothes-free and comfortable relaxing nude with some friends from when I was about 11-12, it just felt healthy and good to be completely open about my body, even when I was becoming adolescent. As a teenager I sometimes showered with other boys at school or whatever after sport, but normally enjoyed just being nude in the comfort of my own room. I feel really happy to be enjoying it much more openly again now and was really thrilled when I found this group last year :)
