what exactly is "sex magick" and what could it have to do with pizzagate?

a rhetorical question.

i saw some posts about oto, and thought ok, i'll look at that knowing certain people have been involved. i go to wikipedia and i read @ https://en.wikipedia.org/wiki/Ordo_Templi_Orientis.

Then I notice something...."Sex Magic[edit] The degrees of the Hermit Triad are of a sexual nature. In the VIII° degree, the initiate is taught masturbation magical practices, in the IX° degree magical techniques related to vaginal intercourse, and in the XI° a form of sex magic involving anal intercourse.[21] https://en.wikipedia.org/wiki/Ordo_Templi_Orientis#cite_note-Handbook-21

i clicked the reference to the book(#21) and decided to search "sex magic" as a term in the following title that was related to the previously mentioned wikipedia page (preview available on google books) : https://books.google.com/books?redir_esc=y&id=rwzttsI9-NwC&q=SEX+MAGIC#v=snippet&q=the%20influence%20of%20aleister%20crowley%20on%20gerald%20gardner%20and%20the%20early%20witchcarft%20movement&f=false

and if you follow that google books link, you will come upon a reference page, click "page 81"...

i never read this book at any major length, but the excerpts make me wonder, so, what is the big secret? how could it be any more of a secret than anything "vanilla" or conventional, or even the outer limits? what could possibly be out of grasp of common knowledge?

also, LOOK AT THE COVER!!!!

in reference to this book, i also found mention of a robin fletcher and then found this article: http://www.news.com.au/national/victoria/news/notorious-paedophile-and-sex-witch-moves-three-doors-from-melbourne-primary-school/news-story/f30c722f11dcc3a4b7abfc0cfae05552

and then this article in relation: THE VILLAGE OF THE DAMNED (IN VICTORIA)<APRIL 4TH 2017> : http://www.news.com.au/lifestyle/real-life/news-life/village-of-the-damned-inside-victorias-most-notorious-paedophile-prison/news-story/aeffacd790e368a4e08ebbd2a3910fb1
