Be really careful with this type of friction. A couple years ago, I got a blister on the hood that caused me to go to the doctor to make sure it wasn't anything else but irritation from riding... I was off my bike 2+ weeks allowing THAT to heal. Owwch. It was caused by a couple things - shorts that were too old to really be useful for padding or for wicking moisture away, wearing underpants seam-side-in under my shorts, and generally being too hot & sweaty there from all that. I did try adjusting the nose of my saddle a fraction, and while that did help a little, the things that helped most were nixing the undees and using Chamois Buttr.
