How do you stop them?
This has never been a problem for me before until this summer when I've actually started riding longer and more often. Been riding the best part of 20 years on and off, and never had one until after Bontrager 24/12 (my first 12hr solo) this July, and then I've done a few long road rides since including a 100 mile sportive yesterday and every time I've spent more than 4hrs in the saddle, guess what's there to greet me the next day!
Just so you know... Personal hygiene is good, bordering on obsessive (I spend way longer in the shower than anyone else I know), I'm using half decent padded bib shorts, a comfy saddle that doesn't rub the wrong way at all etc. I can hop off the bike after 6hrs, then immediately hop back on it if required without any discomfort, yet the morning after, at the crease between the top of my leg and my privates, is a bloody great sore waiting to greet me!
Please, how do I make them stop?!?!
