Is ghusl required after experiencing a shiver upon seeing kisses, and does semen (maniy) exit in this situation without intentional sexual arousal, and do prayer and wudu become invalid due to doubt about the emission of madhiy merely from thinking, speaking, or seeing?

The obsessive doubt concerning the emission of maniy (semen) or madhiy (pre-seminal fluid) should be ignored. The default is that nothing has been emitted and that ritual purity remains, and there is no need for inspection. It is advised not to watch forbidden movies and TV series, to avoid mixing with men except out of necessity, and to lower the gaze in compliance with the noble verse, and not to pay attention to the obsessive doubt about the emission of maniy or madhiy. It is also advised to seek help through the remembrance of Allah and the recitation of the Qur'an, to maintain prayer, to seek righteous companionship, and to occupy one's time with what is beneficial.
