Okay, think about it... Why do ANY of us like looking at OTHER GUYS' COCKS, or even OUR OWN COCKS, as opposed to, let's say, elbows, thumbs, noses, ears, etc??
I read this once, and it makes a lot of sense. It was written by a rabbi.
There is an inborn sense of extreme reverence for the parts of our body that are used to create or nurture (e.g. female breasts) new life. Nobody can teach us to feel modest or uncomfortable when our genitals are exposed and visible to others. (Yeah, most of us who hang around here at LPSG don't seem to care, but most people do care.) So, seeing or showing anogther person our genitals is built in to be an extremely imtimate and private experience.
If you have a foreskin, even FEWER people will ever see your GLANS. Only (except again for those here at LPSG) people with whom are are having sexual activity will ever normally see a man with an erection and his glans visible.
So, SEEING ANOTHER GUY'S GLANS IS EVEN MORE "TABOO" OR EROTIC OR SENSUAL THAN JUST SEEING HIS PENIS, TESTICLES, ETC.
