<s>[INST] i masterbate while seeing porn and fantasize very bad things and totally go mad about it, i also masturbate continuosly like mad for many days and it has also ruined my life very badly as i m doing this from last 14 to 15 years and right now i m suffering from many mental and physical problems [/INST] Hi, The very first thing is not to see porn anymore. Thus, you will not fantasize such bad things. Furthermore, try to stay occupied with work, thus, you won't have to think over masturbating. Next, get engaged. You will get better while sharing your things with another partner. If no improvement, should talk with a psychologist/sexologist to run psycho-therapy séances to get improved. Hope it helped!
