In 1894, a woman named Ruth Smythers wrote a book called "Sex Tips For Husbands and Wives" in order to help young women about to face "the terrible experience that is sex" for the first time.

Here's a quick look at a few of  the helpful hints in Ruth's book.

 

1) "The wise bride will permit a maximum of two brief encounters weekly, and as time goes by she should make every effort to reduce this frequency. Feigned illness, sleepiness and headaches are among her best friends in this matter."

2) "Just as she should be ever alert to keep the quantity of sex as low as possible, the wise bride will pay equal attention to limiting the time. 15 minutes is more than enough time to spoil any man."

3) "Do not encourage him. Nudity, talking about sex, reading stories about sex and viewing explicit photographs and drawings are sinful habits the male is likely to acquire if encouraged."

4) "A wise wife will make it her goal never to allow her husband to see her unclothed and never to allow him to display himself unclothed to her. Darkness is your friend and ally."

As few sales records exist from that long gone era, so it's unknown whether Ruth's book was a best seller or not.
