All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger. We ask Allaah to exalt his mention as well as that of his family and all his companions.
If what you meant is mentioning some matters about your own sexual relation which incites his sexual desires and which does not lead to any forbidden act, like being attached to a particular woman and the like, then this is permissible between the husband and his wife. However, if what is meant is describing a particular woman and the like, then this is forbidden as this is a means of being tempted and being attached to this woman. For more benefit, please refer to Fatwa 87384.
Allaah Knows best.
