Not that they 'use' it, but it is for the purposes of reproducing their own species. It is not a pleasure movement in their case. I am not saying anything against the pleasure movement. I am not interested in saying that you should condemn that or become promiscuous or use sex as a means of spiritual attainment. After that the psychologists have turned that into something extraordinary.
All commercialism is related to sex.
Yes, sure, I am not against that. Please don't get me wrong. I am just pointing out the use to which we are putting that simple biological function. I am not condemning it. It is there, you see.
