Sudocreme, what is that? I wear pants myself, then jeans on top of my shorts.
I'd feel a burke riding just in shorts, my legs are Tippex white!
Sudocreme is nappy rash-cream suitable for sores etc. There are special 'Chamois ointments' available to apply to the nether reagions to reduce chafing during riding, some are mildly anaesthetic. However, Sudocreme is nice and thick, cheap as chips and works a treat, but Savlon, Vaseline, Zinc & Castor oil cream all help add comfort for long days in the saddle, especially when it's really warm like now.
Ditch the jeans, they're dreadful to ride in and you might find that a few rays of sunshine might just sort-out your skin colour (unless albino)!
