Yes, it is permissible for a fasting person to kiss and touch his wife while he is fasting, whether in Ramadan or other than Ramadan, but in the case he gets semen because of that, his fast is invalidated. His fast is broken and he does not have to stop fasting. But if his fast is obligatory, he must make up that day, and if his fasting was voluntary, then he does not have to make it up. [Sheikh Muhammad bin Uthaymeen]
