I am reading the book and find it a great read that reminds me of Diana Richardsons books on tantra.
I do have one issue that comes to mind and raises some questions based on that there is many types of orgasms that women can have and also men.
I work as a sexological bodyworker that does tantric massage on women professionally and work with couples also.
I believe most women generally have an clitoris style orgasm and feel dissatified after sex or mastibation as described in Marinas book.
However when women have ejaculation orgasms and cervical push out style orgasms they radiate energy and love after the lovemaking session for hours and even days. These type of orgasms result in relaxing into the energy and letting go and are usually learnt with strong g spot stimulation.
I was talking with one women about ejaculation orgasms and she said for her that these types of orgams it is a emotional clearing for her and she feels great after sex and less needy and a lot more stable. The funny thing is that she learnt this type of orgasm using a vibrator!
I have been told by some women when they experince these deeper orgasms are not attracted to clitorus orgasms anymore.
Unfortunately only about 5% to 10% of women seem to have these deeper experinces. A lot of women do not even know where there g spot is.
I suppose by question is does having deeper cervical style orgasms drain you of energy and make you more emotional. I beleive not but would be interested in comments from women that do have these experinces.
Men too can have orgasms with no ejaculation as this is my personal experince. You actually do not loose energy and can make love for hours and still feel close to your lover after. Jack Johnson has a good method for learning this.
I would be interested in Marnias comments on my observations.
