Sorry if the title seemed graphic but I need some advice. I just got my first Brooks saddle as a gift. I had a pro bike fit done with this saddle but after the first 3 or 4 rides (all less than 30 minutes) I am having some serious issues with my taint being rubbed raw.

My bike shorts are old, but I've never had this issue with any other saddle (same bike shorts). I realize that the saddle needs to be broken in, but will this even make a difference when it comes to chafing?

I am coming back from a running related knee issue so I am basically starting from scratch in terms of mileage which is a good thing, b/c I wouldn't be able to make it more than about 30 minutes with the what is happening right now. Thanks for your time!
