At 12 yrs old in the mid 70s in a high school locker room. The varsity football team finished practice and was showering when my youth league team used their locker room for "chalk talk", term used to discuss plays and strategies on the chalk board back in the day. It was rumored that one of my friends sisters would date black men, which wasn't very common in our town then. He always said yeah, she just likes their big dicks, not really understanding what he was talking about. While most came out of the shower with a towel around them, One of the well known black players walked out of the shower with his towel over his shoulder, his thick bbc hung out from his body, looping down his thighs and swaying back and forth as he walked. It looked to be at least 8" soft. I remember some of the older guys that knew him would talk about it also. And yes, it was beautiful, that's when I started wondering about interacial and looking at magazines when I could.
