I just finished reading Sheik al-Nafzawi’s Perfumed Garden of Sensual Delight, a 15th century sex manual from what is now Tunisia. The Sheik’s advice is quite impressive compared to what was widely known about sex in Western societies up until about 1970.
Some important points that he stresses is that women are extremely randy and have great sexual stamina, that simultaneous orgasm for man and woman is the norm, that a man should use his hand to help the woman along if needed, and that keeping his wife satisfied is a major responsibility of a husband.
There was however also a lot of news to me in the book, like that short women are much randier than tall women, that a diet of chickpeas and onions increases sexual stamina in men enormously, and that it is a good idea to daub a man’s genitals with the irritant extract of pelleter, Anacyclus pyrethrum.
I read Jim Colville’s 1999 translation, not Sir Richard Burton’s more famous but grossly inaccurate one from 1886. Both are available to those who Google.
