There are 6 levels of erotica
0 through 5.
I don't think level 0 has ever been assigned or used.

The words assigned to the Level are somewhat misleading.
But should be loosely used as the Most erotic View that clip will contain.

Here is an Example that causes you to scratch your head about the level assigned to a clip????
A level 4 clip could be 99% fully clothed, with just 1% of Dropping her Bottoms and Panties and flashing her private parts.
While Most would say this is Not a level 4 clip, It does Fit, The "This is the Maximum Erotic level you will see "

My interpretations of the Level..

Level 0 to 5, each level is used for a different Level of Erotic Exposure

0 - no erotic action - fully clothed dancing like in a public place ( never used in iStripper ) .

1 - means No Erotic body parts are exposed.
2 - basically is Exposed Breasts.. See through clothes, were the breasts can be seen, but fully covered fit this level.
3 - is anything Exposed below the waist
4 - Clear direct Exposure of parts Below the waist, or very Erotic / Suggestive action.
5 - Fully Spread Open / Insertion / Reaching Orgasm ( even if still clothed )


0 - Safe for All Audience to see
1 - no Nudity
2 - topless Nudity
3 - Nude
4 - Full Nudity
5 - XXX
