Jockstraps! Discovered at age eleven my dad's men's large Johnson & Johnson Blue Ribbon athletic supporter drying after laundering above our bathtub at home. Tried it on. Of course it was much too large. Was intrigued by its design which had erotic overtones for my early adolescent psyche. Got really hooked on jockstraps when I had to buy one for 7th grade PE and got a throbbing hardon which produced precum when I tried it on for the first time.
Athletic cups! Saw BIKE jockstraps, jocks with cups, and swimmer jocks on display in the window of a hobby/sporting goods store bordering our town green. I think they along with jockstraps are perhaps the most quintessentially male erotic items around.
I have lived in Washington, DC over thirty years and collected jocks and cups as a fetish item, sometimes in bulk by the dozen to the point that I may have the one of the large private collections of such in the Washington DC metro area.
Circumcised penises! My dad was a Little League umpire in my hometown when I was growing up. Often he would come home from work, take a nap in his easy chair [with a cup of coffee at his side!] and then join us for dinner. After dinner, he would freshen up in the bathroom and strip out of his work [street] clothes. Then he would leap buck naked through the house to don his jockstrap and Little League umpire uniform. I would get excited as an early adolescent seeing the robust nakedness of his trim body. And, as my older brother told me many years later, he also had a tight muscled ass to die for. But invariably, I would be drawn to his genitals, most notably his circumcised penis, the generative organ which helped to bring me into the world. He was circumcised as a neonatal in early March 1914. My grandmother was trained as a nurse and believed in circumcision. In those years, my circumcised penis was a smaller version of his.
Anyway I inherited his physique, his disposition, and penis. In later years, as I entered my thirties, people in my hometown mistook me for my dad. We also had similar religious, even mystical temperaments, as children of nature and lovers of classical music. He's been dead since late December 1990, but he is still ever close to me in Spirit, in my loving recollections of him.
