So do I. I first started when playing Quake 2 because when your're in the middle of a total cluster-plook and you can hear the other's pain cries, having a female voice helps track your wounds.
I use Harpy (red metal Hunter) in Q3, dark-haired Necris in UT, 7 of 9 in EF and the female HEV suit in HL. No biggie.
