Selle SMP Saddles / Crotch Pressure

I have similar issue as your, but with sit bones width.

already booked myself for the Bike Whisperer to talk to them about saddle.

might be worth doing in your case.
Ah, I'm from Bournemouth so that wouldn't be suitable.

In your case though, Specialized do ALL of their saddles in 130mm, 143mm and 155mm widths:
