In spite of sexy wife , i`m looking for another WH

I`m an indian married guy, lived in delhi with my family .I loved my wife , she is so sexy . I like her rides on my cock. She enjoyed much more she fucking hard on me and i also fuck hard in her back. She feel orgasm most of the time and we play hard with loud sound. But in spite of that i can`t understand why i`m always looking for others. I masturbate always but can`t control our thought. When she far away from me i masturbate 2 or 3 times daily. Because of my society reputation i can`t approach to another women for sex and also feel guilty if my wife know about that.I always seen porn video . I spent a hours on window for looking on road to school girls and married women and continue masterbating. God save me from this sexy thought. Actually i like to do sex daily with different women , but its only dream , i know its can`t full fill. If some one have advice for me their most welcome.
