Must one make up the day if the wife refuses intercourse while fasting and she feels aroused and experiences an unknown wetness?

A husband does not have the right to prevent his wife from observing the Ramadan fast. Regarding wetness, if nothing is discharged, the fast is valid. If it is madhiy (pre-ejaculatory fluid), it does not break the fast. If it is maniy (semen) due to thinking, it does not break the fast. However, if it is maniy due to direct physical contact (intercourse), then it breaks the fast.
