Not typical in European erotica, of the 1700s or since is a lot of discussion of the importance of and details about attending to the sexual satisfaction of the female. Men are judged by their stroke count. That count tending to be from a few to many thousands. The ladies will speak directly with each other about who is better and make their preferences clear to a lover. Overall there is a remarkable lack of restraint on a variety of matters sexual. Penis size counts, as does the ladies relative willingness to be active. Virginity is discounted as a thing to be preferred over experience. Side note: There is a rather modern anticipation of turning to surgical techniques to enhance male size. There is a case made for the curvier female as one who has better strength to bare the weight of her lover and as have being in general more desirable than a thin weak woman. Again, one has to be careful as the author may be making fun rather than speaking to common prejudice.
