Yes, Julia. I must say that I am surprised by my own discoveries. Things are never as simple as we may think. Sex has long been maligned as being low and not spiritual. It is also very much taboo, even today. Facebook, for example, does not allow the posting of photographs showing female nipples or the genitals. It is fun to test, as a scientist, various hypotheses about sex and contradict conventional wisdom. Sex is so vital. It warrants more scientific investigations and critical thinking.
