If the reach to the bars is excessive you be forming a very acute hip angle.
This tends to roll your pelvis forward which in turn may put extra pressure on your soft tissue. The goal is to support you body mass with your bone structure vs. your taint.
Try a shorter and more upright stem and see if anything changes. This may make your ass more sore due to the vertical compression. Ass soreness is much better than taint soreness. Taint trouble leads to prostititus. You don't want this. Ever.
As for saddles. There is no ONE saddle that works for everyone. For me the best bet has been the WTB Rocket v, Pure V, Fizik Alliante, Fizik Aerione TRI and the Brooks Swift.
The list of saddles I have tried and really really hated is much longer. Trying various saddles can be very expensive. If you want to spend an hour trying saddles and working on your position I will be glad to help. I have spent the last ten years learning all I can about bike fitting. The biggest trouble with bike fit is that all the various "experts" have conflicting opinions an what is "Right". Based on this conflict I have taken some aspects from a few different fit guidelines and tweaked it for my own use.
I learn new stuff all the time and I get surprised all the time at the very weird body proportions that I see.
Best o' luck
