My first reaction is that the problem is with you, rather than your saddle. But, that said, it is clear to me that opinions on saddles vary considerably. The only problems I've ever had with "breaking in" a Brooks saddle were that it got too soft. It had been comfortable when it was new, but within a year it had gotten soft and uncomfortable. So what you're suggesting, that your saddle has remained hard, sounds good to me. But that's me.

My advice would be to put a different saddle on the bike, but don't get rid of the Brooks until you are sure you have something more comfortable.
