Drawing people with no clothes on is something I actually learned to do in college. Even more ironic is the fact that I was still suffering a nude-o-phobia at the time due to being traumatized by a sexual assault at age ten that had been a repressed memory until the year before I took the anatomy drawing class with live nude models. It was not a class full of guys since you had to have made high grades in three previous levels of drawing classes. There were only three other males in the class, and none of them were significantly more secure in their own nakedness than I was. Virgins all. (What do you expect from male art majors?) But it began my journey into drawing nudes and eventually becoming a nudist.
Drawing a nude figure in a work of art, whether by painting, drawing with a pencil, colored pencils, or digital art on a computer, is an essential step to creating believable figures even after you put clothing on them. Anatomical correctness in structure and proportions are far more realistic when originally drawn by your practiced hand as a nude figure. My mother noted when watching me paint that the pencil drawing underneath looked like a naked body until clothed by a rendering of a body covering, even if I was working from a model or photo that was fully clothed. Being a modest Methodist she often asked if I intended to draw clothes on before painting, which I usually did… especially on pictures painted at home where she would see.
When I am intentionally drawing a nudist picture, I will depict an activity that I enjoy doing in the nude myself. The figure, a male figure, represents me. I do tend to depict myself as an innocent child rather than a fat old man with a beard. I also draw nude girls, usually in the age of innocence, because I don’t have any reason to do porn. And drawing nudes helps me immensely with my own positive body image problem.
Pictures of nudists do not need to reveal sexual features. I don’t particularly enjoy drawing genitals. And the idea of the picture usually does not require those things to be in the picture.
Sometimes the theme of the picture is intended to be humorous. Streaking back in the 1970s always got a lot of laughs, as well as evil looks from old church ladies.
Fairy nudity is also usually given a pass. Why would tiny magical creatures really need clothes?
Some pictures evoke memories of camping, Something we did as a family every summer in the 60s and 70s, though never in the nude… except in my imagination.
And of course, some pictures need to exist simply because the human body is inherently beautiful.
All of this is talked about in the essay I wrote about it in book form on Amazon. It goes into much greater detail with many more illustrations.
