This thread is for discussing the range (or spectrum) of Extras in a strip club. I suggest a 1-10 scale, because it's easy and because it allows suggesting a relative level to the activities in question. Here's my take on the subject, based on what appeals to me:
0.0 = Grinding on clothed customer (that's a Lap Dance, and by definition not "Extra")
1.0 = Kiss on neck or face, but not lips
1.1 = Closed-mouth kiss on lips
2.0 = Dancer's hand on customer's clothed crotch
2.1 = Customer's hands on dancer's clothed breasts
2.4 = Customer's hands on dancer's clothed crotch
2.5 = Over-the-pants stroking
2.6 = Customer's hands on dancer's bare breasts
2.9 = Nipple sucking
3.0 = Over-the-pants mouth-to-crotch contact
3.1 = Light French Kisses
3.2 = Covered HJ
3.5 = FIV
3.6 = Bare HJ
4.0 = Covered BJ
4.5 = DATY
5.0 = Deep French Kisses (yes, they rate this high because they are intimate)
5.5 = Covered FS
5.6 = Stripper-Slide
5.9 = BBBJ
6.0 = BBBJTCNQNS
8.0 = Anal (only covered; otherwise, gross)
9.5 = BBFS
10 = BBFSCIP
