1- It is permissible for a man to enjoy intimacy with his wife when he is fasting, so long as he does not have intercourse or ejaculate. 2- If the wife is menstruating, she does not have the right to be masturbated by her husband’s hand, because that involves touching the impurity, unless that is done from behind a barrier. If the husband is safe from touching the impurity, then there is nothing wrong with it.

Intercourse during the day in Ramadan is haram for men and women while intercourse during the night in Ramadan is allowed. For more, please see the detailed answer.

1- There is no reason why a man should not engage in foreplay with his wife when fasting if he is confident that he will not spoil his fast or hers. But if he is not confident of that, then it is not permissible for him to do it. 2- If one spoils his fast with something other than intercourse, such as eating, drinking, masturbating or foreplay that leads to ejaculation, then there is no expiation but he has to make up for this day later.
