As with any “newish” rider, saddle comfort comes first with time in the saddle. I think many riders give up on bike riding because there rear hurts too much. It can be very difficult to survive the pain if you don’t toughen up the bottom gradually. Finding a seat right off the bat that will allow you to ride for hours at a time pain free is a myth for the majority. After 60 years of riding with many different saddles, at some point during a ride my butt starts getting uncomfortable. That’s just how it’s made down there. Even sitting on a chair or even a couch without adjusting your position now and then can hurt too. Experiment with different saddles and learn ways to lift off and/or move around to extend your rides to make them more comfortable, but most of all gradually increase your time on the bike.
