mr original poster: there is a chance that you've got a bit of an infection of your inner-taint. don't ignore it if you do. normally, a noncyclist wouldn't even notice this. but since you put so much pressure on your taint, then this is why it's like this.

as for saddles: each man needs his own deal, but i like my (gasp) trico split rail. i can center each half under the desired sit bone, and there is NO pressure on my taint.
i myself don't care for the idea that my errectile ability is contingent on the presence of a few milimeter thick bit of fabric.
i also liked the Flow when i tried it.
