I suppose if your cock doesn’t fit in your speedo, then maybe it is too small.

What is the smallest speedo you have ever worn in public?

For me, I think it my black Arena speedos (photo of me wearing them on the right side there).  I really like them and wear them to the pool but not usually to the beach when it is busy.

It is those Arena speedos that I wear when I’m working on my speedo tan.

I have some more pics of me wearing those Arena speedos. Here you go guys.
