What do you think about marrying much younger women as second wives?

I'm in my 50s and not to sound superficial or shallow but I prefer younger women. Not only are they physically beautiful but they have a fresh optimistic outlook on life .... Age causes sin to build up in the soul. Younger women are more innocent and beautiful. I have decided to take a second wife, I would prefer a girl of 16 - 19 years.. I do not care what my first wife thinks. Frankly, It is none of her business and I do not require her permission. It is not required by the Qu'ran or Saudi law. I have seen many young women and I have lusted for them , I want to prevent any possible future extra martial affairs ...... which I know is eventually bound to happen... So I thought why not just marry a young woman... Many of my business clients in Saudi Arabia and Dubai have offered me their daughters and now seems like the best time... After all, I'm already in my 50s, I do want to spend the last exciting years of my life with a young woman, before i lose my lust and virlity... It does not mean that I don't love my first wife, I simply do not desire her in that way, our marriage is more of a friendship.... I love her , I'm just not ually attracted to her. This is why I'm marrying again. A good wife should seek her husband's happiness and if marrying again makes me happy.... then I know my first wife will understand. Its a win-win situation and everyone is happy. I will be happy with my new young wife and she will be happy to enjoy all the comforts of a wealthy lifestyle..... my wife will be happy for us....... i have worked hard all my life to become successful and now i think i should have some fun now, which means , new young wife to look at, and touch.
