You should create simple script:
When you are uploading a new video there should be these options:
1. Few (5-10) pictures of bodies where you choose the figurine of model(s) (separate for man, women and eventually others)
2. Few (many) pictures of breasts to choose these similar for ones in this video (chest for men)
3. Few (many) pictures of legs to choose these similar for ones in this video
4. The eventual option to choose few feet images if necessary.

For users account than create a site when they could choose the ideal-shapes, second optional etc.

Also there should be option beneath the video to report videos that are showing you the bodyshapes you don't want (man/woman/all) to warn/ban their uploaders. Not to delete video there should be option for users to check the good one.
Another option is for you not to have much work with administration of the reports. You should create a site where (ex 3 for reported video) users may check the report and post their own opinion (for checks you could give them few tokens for xlive). When the 2 confirms are right - you should change the bodyshape description and when 2 will say that the original was good - you should warn the "reporter" first and for second time in the 1/2year - turn off his button.
