...very often (but probably not always), the 'taint chafing or rubbing issue is a result of sliding too far forward on your saddle. This results in direct contact between the 'taint and the saddle, which rubs you raw over the course of an average ride. You want your point of contact with the saddle to be the bony protuberances of your ischial tuberosities, not your pubic arch. Sometimes this results from the wrong saddle tilt (too inclined forward). Sometimes from too much reach to the stem and bar. Sometimes, it really does come down to conditioning, so you're pushing hard enough on the pedals to not put your entire weight n the saddle. Often, you need to drop the saddle height a quarter or half inch, to accommodate this new position, sitting on your sit bones on the wider part of the saddle.
It's an area where you need to experiment, and not be afraid to change stuff out, like a stem for shorter reach.
