Is the suitor's discussion of marital relations after the marriage contract valid and natural, and what is the limit at which this discussion should stop?

Since the marriage contract has been concluded, she has become his wife, and whatever is permissible for a husband to do with his wife is permissible for him to do with you. There is no harm in discussing matters of lawful enjoyment between you, while observing what people customarily recognize and avoid before consummation. And be cautious of anything that leads to the arousal of desire, which might push one towards the unlawful.
