I disagree. It is not normal.
It's a normal reaction to having a poorly positioned saddle. There is nothing abnormal about bpt (well, not in this regard anyway!)
Btw, spend some time trying to get a good position on your current saddle before racing out to buy a new one. I'd agree it's a good idea to measure your sit bones (you can do this at home without the Specialized thing), as this gives you an idea as to what width of saddle might suit you.
I feel too many people (myself included in the past) think the answer is always a new saddle when a bit of tinkering, trial and error and perserverance with your current saddle are all that's required.
