How long have the rides been before the butt-achefest begins to settle in? I'm no rando guy but often go a couple hours before a short break and go a couple more. I rarely get out of the saddle (otherwise) on rides less than 60 miles.
ETA: there is a wise piece of advice that says, "the more you ride, the less your butt hurts". If 10 minutes makes you stand up then you might need to ride a bit further and deal with it.
