"Thus I have spent my life in idle longing, without saying a word, in the presence of those whom I loved most. Too bashful to declare my taste, I at least satisfied it in situations which had reference to it and kept up the idea of it. To lie at the feet of an imperious mistress, to obey her commands, to ask her forgiveness – this was for me a sweet enjoyment; and, the more my lively imagination heated my blood, the more I presented the appearance of a bashful lover. It may be easily imagined that this manner of making love does not lead to very speedy results, and is not very dangerous to the virtue of those who are its object. For this reason I have rarely possessed, but have none the less enjoyed myself in my own way – that is to say, in imagination. Thus it has happened that my senses, in harmony with my timid disposition and my romantic spirit, have kept my sentiments pure and my morals blameless, owing to the very tastes which, combined with a little more impudence, might have plunged me into the most brutal sensuality."
