As a guy, doing a #1 isn't too difficult with my bibs - they're stretchy enough that I don't need to take them off to get at my 'undercarriage'. As to #2, unless I ate the wrong thing last night, I'll only need to go at most once per ride per day (with that, then, yes, I'll have to strip down). If I take care of #2 close to the start of the ride, then it usually isn't an issue for the rest of the ride.
