In my longer career as a libertine, during which my invincible inclination for the fair sex led me to employ every method of seduction, I turned the heads of several hundred women whose charms had overwhelmed my reason; but what was always my best safeguard is that I was always careful not to attack novices, girls whose moral principles or whose prejudices were an obstacle to success, except in the company of another woman.
I early learned that what arouses resistance in a young girl, what makes it difficult to seduce her, is lack of courage; whereas when she is with a female friend she gives in quite easily; the weakness of the one brings about the fall of the other. Fathers and mothers believe the contrary, but they are mistaken. They commonly refuse to entrust their daughter to a young man, whether for a ball or a walk; but they yield of the girl has one of her friends as a chaperone. I repeat for their benefit: they are mistaken; for if the young man knows how to go about it their daughter is lost. A false shame prevents both girls alike from offering an absolute resistance to seduction, and as soon as the first step has been taken the fall comes inevitably and quickly.
