After intercourse can a person eat and drink before taking a bath? We were taught not to even touch any utensils as that person is impure in this state, is this correct?

Praise be to Allah, the Lord of the World; and blessings and peace be upon our Prophet Muhammad and upon all his Family and Companions.
Eating, drinking, sleeping, and other normal activities are permissible before taking a ritual bath.For more details please read Fatwa: 82829.
Allah knows best.
