The man may kiss his wife in such a way that they feel the inside of each other’s mouths. This is something that is allowed to be shared between husband and wife. The man longs for the intimacy with his wife. He wants to taste her in the same way you taste a good wine.
10 Et ta bouche comme un vin excellent,… Qui coule aisément pour mon bien-aimé, Et glisse sur les lèvres de ceux qui s'endorment!
