When I first started modeling for artists, I was somewhat self-conscious about how that area of my anatomy might change shape or appearance while I was posing. I was concerned that might be a problem for the artists, the same way it would be if I kept moving another part of my body, and the artists would have difficulty capturing it. But, this is just one of the accepted challenges artists face in working with models, and they just deal with it.
It does happen a lot. Depends on the temperature in the room, or how strenuous the poses are. Often it seems my scrotum is tight when I first begin a session, but it loosens up as we go along. Sometimes in a longer pose, my scrotum will start tight, and then begins to loosen, so that it’s hanging loose by the end of the pose. One time I was posing for a summer class, and it was very warm in the room. I think my scrotum was loose theoughbtgat entire class. They were working with just getting the form of the figure, using the wide side of their charcoal sticks, so no real detail. Some of them drew my groin area with just this long mass there between my legs, which made me look like I was hung like an elephant, (which I’m not.)
Most of the time artists don’t spend a lot of time on this area of the body, (it’s usually this way with female models too, unless the genitals are specifically the subject, which is very rare.) I have had a very few times when I’ve seen an artist just focus on drawing my groin area, usually during a 5-15 minute pose. This may have happened more often than I’m aware, but the few times I’ve noticed it, it was often a female artist. I suppose this is seen by some as the opportunity to draw something that the artist doesn’t have, herself, or may not have as accessible from others they see in locker rooms, etc. to then draw from memory.
The first time I noticed this was fairly early in my modeling career, when I was at a late-night special session organized by university students before the holiday break. I was working with a female model, and on this particular pose we were independent of each other, on opposite sides of the large, 20ft. model stand. When we took a break I was going around looking at students work. This one young woman, who was the quietest in the group, looked as if she’d begun by drawing the female model, who was on the far side of the stand. But, then she must have changed her mind, as I had been standing much closer to where she was, and she had drawn the most detailed and accurate depiction of my penis and scrotum I’d ever seen, outside of a photo. I’d have probably recognized myself if I’d seen that drawing hanging in an exhibition.
Then, a year or so later, I was back in that same studio/classroom, posing alone. When I was looking over the students’ work, after class, I noticed a middle aged woman had focused on me from my waist down to about mid-thigh. Then I noticed the student standing next to her was the young woman from the session where this happened before, in this same room. lol, I thought that was a funny coincidence!
