Since you are new at cycling and the crotch hurts, be sure to lubricate the area of pain (on either side of the genitals). Your crotch is like a newborn's bottom, so use a cream designed to prevent diaper rash. Before each ride apply the cream. Then after the ride, use a cream with zinc in it to make your bottom feel better. Don't use the zinc cream before the ride, just after. Usually at the beginning of the season, I need the creams until I get used to riding. On long rides of 100 km or more, I still use the cream.
