First off, the best saddle and the best shorts will still make your junk hurt if the aforementioned saddle isn't adjusted properly. You have height, fore/aft alignment and angle. Nobody is going to be able to give you an answer without seing your bike setup and how you align whilest on the saddle..
Can't say for sure but google "bike fit" and you'll find a schload of info out there.
FWIW, I have the Selle Italia Flite Gel on two of my bikes and it is a very good saddle, quite comfortable. Most likely that wouldn't be my first guess at the problem, again target alignment as the culprit.
