For riders of advanced age, perineal nerve pain is more likely to occur. It is the main reason I stopped riding 8 years ago. Then, 3 + months ago I started riding again because, due to the pandemic, my gym was closed and I desperately needed exercise. Unfortunately, perineal pain was still a problem. This time, when I searched for a solution, I discovered a saddle that has worked wonders for me. That saddle is the Cloud 9 Cruiser Select Saddle (~$30 on Amazon). It is big, has memory foam cushions and a slot in the middle so there is no pressure on the perineal nerve. Personally I find this seat to be very comfortable and a complete cure for my nerve pain. Just saying it worked for me, your mileage may vary.
