What is the ruling on one who watched pornographic films during the day in Ramadan, then closed them and watched a clip of a boy resembling girls – a "third gender" – which caused him to ejaculate, knowing that he has repented?

Scholars have differed regarding one who ejaculates due to repeated looking, whether it invalidates his fast or not, and many of them favored the invalidation of his fast. The questioner erred by intentionally invalidating his fast through unrestricted looking, and this is among the major sins. What is obligatory upon him, along with sincere repentance, is to make up the fast of that day. Expiation is not obligatory upon him except for breaking the fast through sexual intercourse, according to the preponderant opinion.
