I don't shave my pubic hair but trim it very short, and i do it just because i think it looks much better, and not because i have any grey because i don't. I would also feel a bit self conscious going to a naturist place with it looking untidy.
I shave from neck to knees including pubic and anal. I hate having hair get in the way of tan and such. Also, I did have an operation when 23 and was shaved from arse to belly button, so never been able to bare to grow it back there. I'm now 63 and have no grey hairs down there, only in my beard and receding hairline. :(
Im sorry, but I could never wrap my head around saying shaving makes you look like a child. Believing that is like saying I drink or gamble so I dont look like a child. If thats the assumption about shaving than why even be nude. Because thats what children are comfortable with and you wouldnt want to be nude like a child. Never saw anything like this that carries so much controversy. Yet I see so many adults at nude venues that shave anymore and people find it accepting. Ive never met another nude person that looked at me and said " my God.... Youre bare down there"! Come on people, get over it.
