I'm trying to think of girls that started doing boy/girl scenes as a TEENAGER around the dawn of the DVD era (late '90's) that are still doing B/G scenes today (or quit within the last couple years), never had implants, botox, duck-lips, etc (I'll excuse a minor nosejob), weren't one-dimensional (just did "big fat titties" DVD's, only did girls, always wore latex, etc), and had broad physical appeal rather than a single strong attribute -- by that I mean her strengths were, in descending priority:
1) "Pretty" face -- good enough to use as a DVD cover by itself
2) "Killer" body -- the long/lean kind that makes women jealous
3) "Nice" tits -- round and firm yet also natural and big enough to jiggle
4) "Tight" ass -- perfect for the camera to zoom in on at any time
Attempts at examples:
Jenna -- stared out as the perfect example, then burned out with huge fake tits, duck lips, and a plastic face
Tera -- started at 23 but otherwise perfect, got implants for no reason, got a boyfriend and might as well have quit
There's one I ran across: Careena Collins (found her because she won some awards) -- career went from 1985 to 2004 (started at 18), nice bod, nice tits, if a bit small, although she apparently NEVER got implants despite that. I find that quite interesting -- that a girl could have had a career that long without having impressive tits and never getting implants. Makes me think girls in the business today should study what actually makes for a long career.
Anyways, I think it would be interesting to rent some DVD's that bracket a girl's long career and see how she changed (who didn't get surgery that made her look different) both in looks but also in sexuality and style of performance.
