Assalaamu alaikum Abu Muslim,
(mildly) It is true that Allah and His Prophet have permitted marrying more than one wife, though with certain provisos... but please realize that if you take a second wife, unless both women are comfortable with this, you are likely to cause everyone a lot of grief- including yourself...and your children.
If both women are ok with this, then you could have two houses or apartments next to one another and see all your loved ones every day in a generally peaceful atmosphere (though if you are living in a country that strongly disapproves of polygyny, your children will likely feel this pressure). Otherwise, you will likely see your children less, have a lot of strife in your homes (and if you think your children will not pick up on their mothers' unhappiness... think again. Kids have radar for any kind of problems) and have a lot stress about money issues.
(mildly) It is normal that you have sexual desires. So do most people (including your wife, you know... and if she feels unloved and lacking in company...you may put your marriage in peril). And it is common that when people get a little older and more bound by responsibilities, they may feel an urge to try to hold onto carefree youth a little longer. But if you are just feeling a shallow urge... is it really wise to stir up a hornets nest? If you take a second wife, after your honeymoon period, you are looking at more responsibilities. More conflict. More stress. Less time for yourself, less time for your children, less time for your wives.
(mildly) If you want to marry again for the sake of Allah, marrying someone who is in need (older, less attractive, financially in a difficult place, with kids who need a father figure, or other difficulty...), and with the full understanding of the implications of this marriage, then this is something that you could perhaps explore (and if this is the case, your wives are more likely to get along, incidentally). You are right, Allah SWT has Permitted taking up to 4 women in marriage. And the Prophet SAWS certainly helped women in this way through marriage. But there are limitations. And depending on where you live, there may be more limitations than others. I would advise that you read up on fatawa from your country. And that you take legal and financial advice for this step before you ever even broach it with your wife. (smile) And of course, that you pray sincerely for Guidance.
May Allah, the Grateful, Help us to see the good He has Gifted us with.
