Was there a specific event in your life that “turned you on” to swim briefs?

[Schoolspeedo]

At school when a friend lent me a real speedo swim bikini of that very light fabric which felt so flimsy against my skin and gave me a very obvious bulge, I ditched the heavy nylon bathing costume, never to be seen again! The sheer thrill of feeling my cock free to bulge out and see it's form when the bikini was wet, was enough to get the blood flowing and when someone brushed against it, as invariably happened when I was standing in a line waiting to swim, the was a tingling feeling caused by the fabric which then increased the size of the bulge. Standing looking in the mirror after a shower and seeing the bulge along was exhilarating as was the stares of my grandmother.
