Saddle - inconsistent discomfort

[Catrin]

What is the difference between a Brooks 17 and the 17S?

As mentioned in an earlier thread under "new riders" I started having inconsistent discomfort with my Brooks last week, but last night and tonight it was nothing but consistent. Tonight I tried lubrication, applied it directly the the chamois. There was so much tingling from the cream that I honestly can't say what the saddle felt like for the first 10 miles...

For the SECOND 10 miles, however, the discomfort was very apparent and it focused on my girly bits - more toward the front but by the end of the ride all of my soft tissues were complaining. I couldn't figure out why this was suddenly a problem, it is getting worse the longer I ride.

Then it dawned on me, there were so many fitting issues with this bike that prior to the reconfiguration of my LHT, I literally could not ride it longer than 5 miles at a time. So of course I didn't notice any problems because I was having a lot more pain in other places.

I also realized that my saddle has this stamped on it:

"Brooks
Ladies Standard
B17S"

If this is a standard B-17, should that 'S' be there? Do I have the saddle I think I do?

My Bontrager feels better than this did tonight...but perhaps the Brooks is still breaking in?
