Query: Rate this book XXX for explicit sex scenes

I found this book not only boring, but absolutely not suitable for anyone under 18 because of the (to me) gratuitis and explicit sex scenes involving, woman/woman, man/woman threesome, etc. I absolutely had no expectation of this when I began reading. Also, the book is very boring, very little in the way of any "action", mostly a lot of (I presume) the author's philosophy. I skimmed through to the end, in hopes of something interesting occuring, but to no avail. I will not buy any of his books in the future!!
