Manual of Classical Erotology…
“ I submit myself to a man and a woman at the same time; but nevertheless with the organs which are left free to me I am still able to commit a worse ignominy. All my limbs are polluted; then shall my eyes also take part in my enjoyments, they shall be witnesses and judges. What I cannot see in a natural way let me see by the help of art, so that I may not be ignorant of what I am doing. No matter to me that Nature has provided man with such insignificant organs of voluptuousness, the same nature which has furnished animals so well; I find means to deceive my passion, and to satisfy myself. ”
