What is the ruling on oral sex between spouses, and what is the ruling on eating beef slaughtered in Germany after the cows are struck on the head with an iron rod before their death?

Conjugal relations should remain within the bounds of Islamic etiquette and noble morals. What was asked about, namely suckling the wife's breast, contradicts refined manners and sound human nature. It is safer to abstain from it because it is likely to involve touching and swallowing impurities, which is forbidden if the impurity mixes with saliva and goes down the throat. There is no difference between the period of menstruation and purity in this regard.

As for the second question, animals that are stunned lawfully before their death are permissible to eat. However, those that die before being slaughtered are considered carrion and are impermissible to eat. Striking a cow on the head with an iron rod constitutes torture, and the Prophet, peace be upon him, commanded kindness in slaughter. Therefore, it is correct to avoid this action unless there is a dire necessity for it.
