Okay, repeat after me, the number one rule for LD comfort on a bike.
NO SEAMS
Buy yourself some wicking bicycle shorts with NO SEAMS anywhere where your butt touches the seat. Even better, spring the bucks for some LDComfort shorts and gear. It's worth the money.
Continuing out from your underwear, no seams, I wear some cheapo breathable nylon track pants under my riding pants (if I need anything between my underwear and riding gear).
With seams, blood pools and creates 'hot spots' that turn into genuine sore spots. NO SEAMS you don't get them.
Oh, my background, I'm a LD Rider, I've done well over a 100,000 km in the last 3 years on my FJR alone. I've done an Iron butt (1000 miles in less than 24 hrs).
My butt is no longer the issue on a long ride. With regular tighty whities or briefs and jeans, I'm done after about 5 hours. Oh ya, don't forget to move your wallet if your a back pocket carrier! That piece of cowskin has put more money in chiropracters wallets than anything.
Learn to stand up on the pegs and stretch. Stick your legs out in the breeze and give your ankles a good rotate. Do this BEFORE you start feeling uncomfortable.
Wear ear plugs, hydrate. Ride the planet.
