I ride a Brooks B.17 and am responding to your post because you said you have ample breasts...kidding...lol. Listen to the good advice above...Roadwarrrior's in particular.
The B.17 as much as I like it may be all wrong for you. The thing with the B.17 is it can cause some pain if not sitting fore/aft on the right spot...bacause it gets wide quickly near the rear and likely is aggravating your anatomy...may simply be the wrong seat for your sitz bone spacing. Bike fit is not an absolute science and why it compels such debate on this forum. You also may prefer a more upright or comfort bike geometry which may be easily accomodated with a stem or set up change.
It takes a while to find the right fit on a road bike. For most of us it is a work in progress.
Pain tends to go away the more fit we become as well.
Good Luck,
George
