Mens Thongs
I have a big bum for a man - I am 5 feet 7 inches, 145 lbs, 37-33-39 and thought thongs might be right for me. I found those available in the shops too small at the front to accommodate an erection, ironic since the narrow strip of material caressing the bum crevice is supposed to stimulate one; also the material was too stretchy to get a firm grip on my bum crack. So I set to work on an old sewing machine and made some out of firm, white nylon that was easily washable. I often wore these when going swimming. If there was anyone in the men's room who appeared to be interested, I would spend a little time wearing only a thong. Sometimes we would retire to the showers or to a private cubicle .....
John's fishnet item, above, inspired me to wear mine to the clothing-optional beach last week, walking about 600 m along the roadside from the car to the shore and a little further to the CO sign (more or less). Still love the feeling of the breeze touching everything while being notionally 'covered'. Was passed by a few pedestrians and cars while walking; not sure how much the car occupants could see from the short distance.
