Tighter shorts should fix the balls issue. You know they're tight enough if you can barely get them over your butt. Your balls should be pulled up and held out of the way by your shorts. I usually reach down there and yank them up just before I ride. Kinda hard to be inobtrusive about it though. I probably have 10 pair which I cycle through, choosing the short according to the ride. Just the right shorts may take a bit to find.
I rode the bike at a local park today for I guess somewhere between 5-10 miles and did a couple more little tweaks to the saddle but I am pretty satisfied. When I was crouched as low as I could go in the drops my knees were almost hitting my elbows. I do think I could go for a 120mm stem eventually. I measured the top tube again and its 60cm, 23 1/2". So the frame is really tall (64cm) but not all that long. With the 100mm stem it's still pretty upright while I'm on the hoods. FWIW I have the saddle and bars adjusted to be comfortable primarily on the drops, and since the bars are comparatively high I think that's fine. The Raleigh I've been riding has a 57cm top tube for comparison. It would be very strange to think that a longer reach is what I should have been working toward but I was trying to sit on my butt before, like on an upright bike, so that sure would limit my reach. It sure is confusing, though, the bike shops put me on a 58 with an ETT of 56-57, the fit calculators all seem to want me on a 56-57 ETT w/120mm stem but I seem to be comfortable on a 60 TT w/100mm stem, maybe longer. That's a remarkable reach disparity.
