The same women (doctors included) who insist all males are built alike, wouldn't all wear the exact same bra, would they?
I'm finding at age 64 that I need to put my weight on my sit bones. My male parts are 2 to 3 times the size of the average guy's, roots included. When I allow much weight to rest on my penis roots, I have problems - the least of which are numbness. Another result has been growing strictures, or blockages, in my urethra. That means urine can't pass. Which can be life threatening. I go to the doctor for it now, and I sit on my sit bones.
Bottom line: We're not all exactly alike. Don't let them tell you something you know better. Go to a good local bike shop, and try some saddles for comfort.
