Masturbate 30 time and sex 2 times month

I am married. My physical requirements is to have sex daily or the other day. My wife is not sexually active or you can say get actjve after every 15-20 days. Rest days i do masturbation in front of my wife and she is okay with this. She even dont help me in this. Even if i do sex couple of days a month,my wife gets quick orgasm in 5 minutes and i have to masturbate again to acheive my orgasm. Our relation is like this for past 6 years. Inside my mind i want to have extra marital or prostitution but i avoid due to scare of diseases or trust. We fight many times and in anger she says get sex from outside. Even Yoga and spirituality not helping. I am not sure how can i decrease my urge or increase my wife urge? Are there drugs to decrease sexual urge?
