What are the limits of a man's enjoyment of his wife with whom he has concluded the marriage contract but has not yet consummated the marriage, and what is the ruling on speaking with her over the phone, engaging in sexual conversation, and masturbation?

If a man validly contracts marriage with a woman, she becomes his wife, and all that is permissible for a husband with his wife becomes permissible for him with her. It is permissible to speak with her over the phone, even about sexual matters, as long as it does not involve masturbation by hand. However, it is advisable to avoid discussing sexual matters over the phone because its consequences are not secure. Likewise, one should hasten to complete the marriage and consummate it.
