The exception IMO is drafting women, if they look uncomfortable you gotta do your best to drop em, but frankly most women who are fast enough to warrant drafting know what they are doing and are comfortable unless they are a triathlete. I've had some guys give me the cold shoulder when drafting them, but they never slowed down to make me pass so I know its an ego thing on their side. Its really not that complicated, its part of cycling. Also, if you want them to pass you you can flick your elbow out to signal to them to pass.
