You don't look comfortable on the bike. You are reaching way too much to the bars, the saddle is too low, and too far forward. The delicate area is stressed because that is where all your weight is. Maybe find a Serotta fit kit store? And more importantly, a good fitter. Do yourself a favor, find the best local bike shop in terms of fitting and get fit soup to nuts. When you lose weight on tour, then get fit again......
