FWIW, I bought two identical B-17 saddles and noticed right away that one of them was significantly more comfortable in the perineal area than the other. The only difference that I can see is that the more comfortable saddle has slightly less tension on the leather. I tried loosening the other one, but it's at the stop and I can't loosen it any more than it is, so I guess I need to wait for it to break in more. Both were bought at about the same time and treated with proofide in the same way.
So despite advice to the contrary, I would try loosening the tension a little to see if it helps. If not, just crank it back to where it was.
