I like 'em too - like seeing and wearing if not Speedos then other similar brands; and it rather amuses me to see all these threads about "Speedos".
For I have always lived at the sea-side, most of it so far in a holiday resort. so I see "Speedos" for what it is: merely a brand-name for a particular make of swimming-trunks whose style is not much different - maybe slightly briefer - from what males of all ages have worn for decades irrespective of the name on the label.
I recall seeing something on EP about men being very wary about wearing these garments on the beaches of one particular US state, apparently because they were considered almost obscene. For Goodness' sake, they are only swimming-trunks!
