Burchard of Worms

'Have you had sex with your wife on a Sunday?' You shall do penance for four days on bread and water.'

'Have you had sex with your wife or with another woman from behind doggy style? If you have done this, you shall do penance for ten days on bread and water.'

'Have you tasted your husband's semen in the hope that because of your diabolical deed he might burn the more with love for you? If you have done this, you should do penance for seven years on the legitimate holy days.'
