Oooooooowwwwwch. I'm sorry you are suffering so much in the saddle. Ack!

OK, in reviewing some of the info you've shared, I can make a few suggestions based on my riding experiences.

1. Bike fit--Thou shalt not reach too far for the handlebars. Are you having pain in your shoulders? Neck? Back? If you are reaching too far forward, that will put pressure on your girlie parts, too. You might want to try a shorter stem either with an adjustable stem or a regular stem. I found that a 80mm stem did the trick for me.

2. Saddle--Thou shalt not go numb in the saddle. If I remember correctly, the Dolce saddle does not have cut-outs, just a padded nose? Have you considered trying one of the Specialized mtb saddles like the Ariel or Lithia in the correct width? A Specialized dealer has a butt-o-meter to measure the distance of your sitbones and can recommend some of the saddles that are available in 3 different widths. Or consider maybe a Brooks or Selle An Atomica? Also, your saddle may need to be adjusted so that the nose is pointed down just a little. And check the seatpost--it may be raised too high also.

3. Shorts--Thou shalt not use the wrong short. Maybe you are one of those that needs a thinner chamois. Some of the PI's have thicker chamois and I have found that it sometimes bunches up during a long ride. I now order PIs in a smaller size. I also use Terry shorts because the chamois is thinner and has 4 way flex.

Hope these suggestions help. I know my fit was trial and error and I've got it dialed in late in the cycling season. Good luck and let us know how you are doing.
