Speedo thought

My reaction depends entirely on who's wearing them.
and where.

swim team guys are fucking hot. fat guys are not.
and a speedo can reveal that a guy is disappointingly small--although it can also really accentuate his amazing physique (see what I said about swim guys--I can give them a pass and assume they're just a bit cold if they have those abs and those shoulders and omg...)
but let's say I saw a guy with something really massive in his speedos... at a public pool, with families around... I'd assume he was a creep. Minding his own business on a beach in Italy or climbing out of the pool after doing some laps, I'd be very intrigued.
