Don't shoot the messenger here! Yes, I've got bolder as I've grown older. I threw caution and clothes to the wind, so to speak and got involved in a few Spencer Tunick installations (mass nude photography). I then went on to date a naturist. I ended up marrying a naturist.
DH and I just after we got married (au natural in a desert), took part in a life drawing session - as a couple. We have since been to a few body painting events, joined a naturist walking group in Germany two years running, and now that we are living in France - living as much of life as we can in the buff, including gardening in buff (with sunscreen and sunhats of course). Hygiene? No issues with sitting on towels or on a sarong. Chilly - on go the clothes!
To be honest, I came from a very religious and sheltered background. Wow, how I have changed!
It's not everybody's cuppa tea, so to speak, but I feel my change of lifestyle has made a better impact on my health and mental health. I'm a happier person. Yes I no longer have a perfect body but I've accepted myself as I am. And if I go to a naturist beach or event - nobody cares a jot what I look like nor do I care what anyone else looks like. Everyone is 'beautiful'.
As I say - don't shoot the messenger down in flames.
