The first time I rode my B17 (regular), it rubbed my girly bits raw. I couldn't sit at work very comfortably, everything hurt. This continued for about 3 or 4 more rides - it did slowly get easier and easier, but it really hurt. Out of desperation, I googled up ways to break in your saddle, and someone suggested soaking a towel in water and placing it on your seat.

Whatever you do, don't do that!!! Just tough it out!!!! I did put the towel onto my seat for about 10 minutes, and it did break in just perfect by the very next ride, but I noticed a weird little rough spot the other day - and I'm pretty sure that the wet-towel break in was the reason. I proofhided it, so hopefully that'll prolong the saddle a little bit, but I really don't want to replace this saddle now that it's perfect.
