I used to masturbate and i felt something at the other times. Everytime i used a pantyliner and i did that, i always saw a white spots which is discharge. Do i have to perfom a ghusl? Because i don't know if it's actually my discharge or orgasmic sexual fluid. I've been doing this for a long time and i afraid that all of my prayers nor fasting that Allah didn't approve whatever i've been doing.
