Something you will often come across reading old sexological texts is old prejudices. Here are two about prostitutes (females who sell their bodies for sex):

1. Prostitutes lack "the feminine sense of honour".

2. Prostitutes lack any pleasure from sex.

Why do I call these prejudices? Because the "feminine sense of honour" adverted too is entirely invented by men to keep them chaste and monandrous and because these same men do not wish to conceive that a woman might enjoy sex, not least with a paying stranger.

When the first sexology texts were written (overwhelmingly by elite educated men) it was believed that a sexually enthusiastic or adventurous woman was pathological or immoral or both.
