Perhaps not for me

I went to the book store yesterday and saw a book on tantric sex and thought hm! Then I started to look at it. Apparently you have to read a book, set up your room with crystals, pillows and flowers, exercise (get permission from your doctor), meditate. It said ideally go for a light jog first to warm up (seriously!?) and then have a good shower, gently gaze into each others eyes while "exchanging energy" and practice 3-5 times a week. Honestly? Who has the time?
