1. Sometimes I watch lustful scenes so a fluid comes sometimes in large quantity and when after some hours I go to the washroom the fluid would be white and sticky (i think by the time it gets white) but it didn’t came from gush (force)? Is it obligatory to do ghusl?
2. Sometimes I doubt wheter it came from gush (force) or not? What is the difference between madi and semen ?
Please clear this doubt as sometimes I change my clothes regularly

Ruling 345. If some fluid comes out of the penis and the man does not know whether it is semen, urine, or something else – in the event that it comes out with three characteristics: it is accompanied by lust, it comes out with a gush, and one’s body feels weak after it has come out – then that fluid is ruled as being semen; and if none of these three characteristics are present or if even one of them is not, it is not ruled as being semen. However, in the case of a sick person, it is not necessary that the fluid comes out with a gush or that at the time of coming out his body feels weak; rather, if the only characteristic present is that it comes out with lust, it is ruled as being semen.
