I'm most attracted to a guy's upper torso, including his abs and chest. I equate my feelings about a guy's chest with a straight guy's feelings about a woman's tits. I remember thinking in high school what an advantage gay guys had in being able to see bare chests of guys, whereas girl's had to cover their tops.
After the torso, I'm attracted to the face, the cock, the legs and then the ass.
But if I see a hot guy on the street, or at the gym or beach and I can see some bare flesh on his stomach or chest, I find myself very interested.
There was one 19 year old kid that used to work for me in my old warehouse manager's job, and one hot summer day, he was the only guy working in the warehouse on a Saturday. Where he would usually wear a T-shirt, on this particular hot July Saturday afternoon, he was wearing a long sleeve green shirt, (I can picture him in it exactly, seven years later). He had the shirt unbuttoned and he came into my air conditioned office to talk to me. He sat in the chair facing me to the left of my desk. I could see his smooth chest, and his hard abs with a tiny line of wispy blonde hair running from his navel to the top of his jeans. He caught me staring and asked me why I was staring at his abs. I was embarrassed and don't remember how I replied, but I'm sure he knew. I wasn't "out" out a work, but it became obvious to the employees that their boss was gay. I never made any sexual advances to any of my young straight employees, but I did befriend a few.
I digressed from the topic at hand, but I can still visualize handsome, straight, young Mike sitting there, and me staring at the exposed flesh on his "
Logan like" body.
