I am male and four of my bikes have B17's on them. Obviously they work for me. My (female) riding partner is a slender 5'2 and she tried a B17S and it was too small for her!! It is really a small saddle. The B17 fits her better. She opted for a Terry anyway.
If you happen to live in or near Ventura County CA, I can lend you a B17 for a bit to see if it works for you.
