Testament to how vast LPSG repository can be, it took me seven months to reach this forum. Well, I have always been attracted to them, even before I recognize myself as gay. I mean, I could not be attracted to the guy but a nice bulge is a nice bulge. Also it has to be something with the clothing/ covering of it. At first I thought I had to do with shininess of the fabric or how snugged it was- repo pants, lycra shorts, meggins, speedos, leather, denim -, but what about freeballers on track pants or basketball shorts.
What comes to mind is definitely sexual or arousing but to me more the like of a first flirt or insinuation even if/ even more so if they are aloof of it. It can be mesmerizing if an outline is shown or if it shows movement, again even better if it's a hardon that can't be controlled. I guess there's a voyeur side of it too.
On the exhibitionist side, I try to show off my bulge too and get super excited if I catch someone doing it but I have to say only a few times it has led to a random encounter. I got a steel cockring too just to accentuate my bulge and would wear it now and then just for the sake of showing some extra bulge.
I know I got carried over but what do you expect of a confessed bulgegawker.
