Is it forbidden for a husband to lick juice and milk off his wife's body during intercourse, including her private parts?

It is permissible for spouses to enjoy each other's entire bodies, unless it is during menstruation or postpartum bleeding (nifas), or anal intercourse, or during the state of ihram (for pilgrimage), or while fasting. As for placing food on the body, it is not appropriate due to the waste of money involved and the lack of respect for food. This is further emphasized if it is placed on a place of impurity, and scholars have explicitly stated the impermissibility of using edible items for istinja' (washing after defecation).
