Q: Is oral sex permitted in islam? Is it also permitted to lick/kiss private areas between spouses?
A:No it is not permissible because precum will most probably enter the mouth and precum is najis (impure). Also the mouth is used for recitation of quraan, etc not for such degrading acts. Licking will assume the same answer. As for kissing this will also be undesirable.
