Sexual Alchemy, Its an older book but anyone read it? Options

I use older rather loosely of course since there are much older books in circulation. But I saw the reviews on Amazon and was curious what everyone here thought of the book? Does it serve its purpose? Is it just about having sex with spirits? Who are the children of Lilith?

The book sexual alchemy covers a couple of areas. First it goes into creating sexual servitors, pretty much the same information covered in the book: Magical Use of Thought Forms: A Proven System of Mental & Spiritual Empowerment.

Secondly the book goes into detail about the oil of Lilith (Pre-ejaculate from both sexes) and the White and Red Powers (Ejaculate and Menstral discharge) and there occult uses. A good read, but since it is now out of print I would get the currently in print book above. Since it covers the same material. The only thing unique / not included is the practice of meditation on the left eye of a picture (Of you dream lover while sending thoughts of love to the picture)

Personally no success invoking my own sexual servitor (Haven't spent a lot of time on it) however they do exist so someone with the right attitude should succeed.
