I sometimes masturbate my self and something like urine comes out is that the mani or Madi and most I perform guhsul jazakallah kairan
If it is manī then this requires ghusl. Manī (semen) is ejaculated in spurts and there is usually a feeling of pleasure when it happens. But if it is madhī then this requires no ghusl. Madhī is a mucus-like fluid that comes out slowly and continuously during sexual arousal.
Note that both manī and madhī are pure, so if they fall on clothing, one can still pray in those clothes without washing them, according to the scholarly opinion I prefer. But like I said, even though manī is pure, its ejaculation necessitates ghusl.
