Discussion: Is there a model that unites all the existing categories of pornography into main categories?

My husband and I, 40 plus, regularly watch pornographic movies. We have seen that there are hundreds of categories of pornographic films.

Following your question, I tried Google Answers and found no attempts to produce parent categories in a unified model for the entire pornography industry. At the same time, I tried to put together a method that unites all the main categories and found that all the titles of existing and future porn films can be classified into 13 categories. (Plus one technical category) These 13 (plus 1) categories make it possible to produce almost infinite numbers of pornographic titles.

The 13 main categories answer four key questions: my favorite sexual orientation to watch, the preferred plot and participants in the film, the sexual behavior of the participants in the pornographic movie, video length, quality, rating, upload date, etc.

The main categories are as follows: (The pornography industry does not necessarily use these categories.)
1 Sexual Identities and Orientations. (LGBT.)
2 The plot of the film. (Endless possible scenarios)
3 Single, couple, group.
4 Full nudity, partial nudity, sexual stimulation without exposure of genitals.
5 Age groups. (Young, mature, old)
6 BDSM - masochistic with and without control.
7 Body features. (Fat, thin, small breast, large breast, large penis, etc.)
8 Ethnicity, origin, and religion (blacks, whites, Asians, members of all religions and nationalities.)
9 Sexy clothing and sex aids (vibrators, sex dolls, etc.)
10 Professionals, amateurs.
11 With and without ejaculation, orgasm.
12 Sex is forbidden. (Mostly In the family)
14 Animated sex fantasies. (As imaginative)
(*) Technical - Video length, quality, rating, upload date, etc.

Each pornographic film has three options to be associated with the top 13+1 categories. (Plus - Yes, Minus - No, or 0 - neutral.)
