What is the ruling on fondling the penis until madhiy (pre-ejaculatory fluid) is discharged, then stopping before the emission of semen, knowing that the ruling on masturbation is prohibition?

Performing this act intentionally for masturbation is impermissible, even if no semen is discharged, because it is an initiation into a forbidden act. Some scholars hold that the displacement of semen necessitates ghusl (ritual bath) and breaks the fast of a fasting person. Furthermore, this act leads to physical and psychological harm.
