Im a girl guiatrist.. never bothered about fret width, of course i have long thin fingers, which guys don't so theres benefits in both sexes.

plus i dont think that ur hands really effect how u play, perfect practice does however, if u keep at it, the webbings on ur hand will stretch more.

I mean what do female bass players do then ???? and bass is much harder to play trust anyone who has tried to play bass - i have and after a half hour my fingers feel like they did when i started out on guitar.

I play both acoustic and electric, i have 10 gauge strings on my elec, and 12 gauge on my acoustic. i have been playing for about 2 yrs, and im not the most dedicated of students, sometimes i go for weeks without touching a guitar........otherwise id be a lot better than i am now hehe
