I had lots of girlfriends but my criteria were always the same – access to her tits, she must be willing to suck me (at least as a prelude to fucking) and she be willing to spread her legs for my dick. I jacked off regularly (which I always kept to myself) and because I was a jock it was pretty easy to find girls. Then things really changed around mid-year when I was a junior in college and Tim must have been a senior in high school. But, we didn’t parade around naked with a hard-on either. We certainly saw each other taking a leak, getting in and out of the shower, getting dressed, etc. As most brothers are, we were fairly open with nudity. My brother and I had separate bedrooms but shared a bathroom. It all started when I was still living at home. I was straight as an arrow and thought only of pussy until my little brother played with my mind (and my cock and my ass and my everything else).
