You just don't seem to be having fun anymore.
Go out and ride your bike more. Psychobabble doesn't suit you.

Back on topic... I put a B-17N on my Lemond.
At first, yeah, it was a little hard and the first ride -a short one- was a bit worrisome.
The second ride, it a ll started to make more sense and with each ride, as the slickness wore off and the leather began to relax, I liked it better and better. It wasn't long before I took it out on a 40 mile ride where my stock Bontrager made me doubt I would ever ride any kind of "real" distance and i knew that would not be an issue anymore. When I sold the Lemond and bought my Giant, I kept the B-17 and put it on.
Now, I can feel my butt settle in... like a well-worn pair of jeans.
Then -sacrilege- I put a B-67 on my Jamis.
Maybe it's the springs but the saddle is taking a little longer to mold itself.
It's still plenty comfortable, though... but it is heavy.
