shower after ride use gold bond when not wearing bike shorts be sure to use bag balm or some other sort of salve when you are wearing bike shorts stop shaving your nether region
I prefer gold bond when I am in my regular clothes and under wear it keeps things comfortable
and I use hydrocortizone/ diaper rash cream when wearing cycling shorts and going on long rides
when you shave you nethers it also heightens the chances of a folicular infection as you have already broken down the outer layers of the skin not to mention riding can turn regular ingrown hairs into really nasty boils
just my $0.02 YMMV
