Love this question. The answer is yes and I always have been turned on by it. Years of sending gorgeous women and hot guys to the shadow realm and feeling the power that I have over them in those numerous, fleeting moments have cemented that realization.
But as of the recent past, ever since I became ripped, I've been getting more turned on by my body than my cock. Whenever I have a guy on his knees worshipping my abs, or have a woman open up my shirt while I'm driving just to lick and caress my abs, it hits differently. Maybe its because I was blessed with a big cock genetically, but I had to work hard for my body after decades of neglect and ill-discipline. Seeing the admiration that others have for a creation that I spent thousands of hours crafting, its more fulfilling.
I can say that confidently today, but if you spoke to me five years ago, I couldn't possibly imagine anything but my cock to be my greatest physical treasure.
