How to call the girls, without beeing despective....

As non native speaker i wonder how to call the girls without beeing too despective to them...
Girls,ladys,actress doesnt get the point.
Slut,bitch,whore might hurt the girls if they going to read it.
In my head this words are not despective at all, but some might find it agressive and not very charming...
I have great respect for the girls,who please us, i have great respect for those who act like having fun during the action...
Needless to say, that i dream from one ore another .....
Whats the right word for a nasty girl doing all the LP stuff with fun???
Is there a difference between older women and barley legal teens????
