As a rule, bontrager saddles are *boink* in my book.... get something with a decent cutout. Many even those of the male persuasion ride cutouts these days.
I now ride Selle SMP and highly recommend trying at least the affordable TRK version.
Raise the stem (higher angle), got any spacers left? Did daddy build too big a bike? (nice of him to get a growing young lady a carbon/dura ace setup
) ETA: OTOH, maybe he intends you to "grow into it"? Did he account for female anatomy i.e. short torso compared to legs?
