Al-jawab billahi at-taufeeq (the answer with Allah's guidance)
In the fast of Ramadhan, if you have sexual relations intentionally in one of the private parts, you will have to repent and do Kaffaarah, which involves freeing a slave and if one is unable to find one, then fasting for two months continuously, and a person is unable to keep these 60 fasts for some valid reason e.g. continuous sickness, then one has the option of choosing from one of the following four:
1. Feed sixty poor people to their fill for two meals, or 2. Feed one poor person two meals a day for sixty days; or 3. Give 60 poor persons 3 1/2 Ibs. (approx. l.6kg of wheat or its value in cash or food grains) 4. Give to one poor person not less than 3 1/2 Ibs. of wheat, rice or food grains, etc. to its value or cash for sixty days.
(Nurul Idhah/ Talimul Haq)
*There is no Kaffarah (expiation) for spoiling a fast in other than Ramadan.
