I am a big fan of gear that shows off a man's bulge. Viewing a guy freeballing in some shorts with his cock and balls swinging in the shorts is so hot to watch. If he is cut and the shorts show the outline of his cock head-- wow that drives me crazy. Also enjoy guys wearing some tight, body clinging lycra / spandex gear-- there is no hiding the cock and balls in that gear-- you can often make out the veins of the cock shaft-- so fucking hot-- love seeing cyclists in their tight cycling kits, a runner in some lycra / spandex shorts or running tights and triathletes in their tight skin suits! Swimmers or divers in their speedos-- even better when wet and clinging to their bulges.... so hot.
I have devoted a blog to images of the above... check it out
