I have a 2.1 and my first ride was on the stock Bontrager saddle (DH said, "try it. You might like it. It's white. It looks cool. BLAH) 40 miles and I couldn't ride for a week.

Ditch the saddle immediately.

PS. Hopefully, KnottedYet was kidding about riding naked. Don't try that. Not for amateurs (I've heard).
