My friends and I call that problem a "twisted sister". One reason why I hate to use the bathroom while riding... I just never seem to get my short back on right and everything gets "tangled" up and uncomfortable.

Just a thought, make sure you are wearing a good cycling short that fits properly. Do not wear underwear. Try using a cream or ointment such as Assos Creme or Chamois Butter to lub the chamois. That will keep the friction and irritation down. I also make sure before I ride to use corn starch baby powder "down there" to keep things dry.

Many cyclist talk about "seat time". After a period of time, everything seems to "toughen up" and sitting in the saddle for longer periods of time become more comfortable but once the rides get longer and longer, the problem may re-occur. It's just the nature of cycling.

A good saddle is helpful. I started last March (2005) riding with the Terry Butterfly and alot of my problems went away. This saddle may not work as well for you but some saddle will. Do some reserach. This website has lots of info re saddles and saddle sores.
