I had prostate issues and discovered padded liners which helped when it was bad, and now post successful treatment, are very comfortable. Though it does feel like a filled diaper at first

I have MTB and other wicking shorts for the warm weather and “active” slacks for the cool days. The slacks are often called commuter pants. I feel these are appropriate as a senior. I just feel Lycra is pretentious for someone my age on a hybrid bike. My wife, though, thinks the tights are hot.
I do like cycling shirts for their bright reflective colors, cooling and pockets.
