Bullshit, men go for polygamous marriages because the wife doesn't fulfil the requirements like not producing enough kids or not giving enough sex. These are the main reasons why polygamy is common within the Somali community.From my understanding, some men are more committed to fidelity and monogamy than others. Do you think I want to risk ending up with a lewd and impulsive maniac? Those expectations should be clarified before the marriage.
A man with a strong capacity for delayed gratification is preferred. I would like that trait to be passed down to his offspring.
Also, there are men who despite having a libido-charged wife still step outside or get a different wife. Sex isn't always the panacea to a marriage. Though as you've stated I see how it would be important to men.
Now back to the topic. You're not a man and you still don't respect our nature. That is the problem. Sex for us is extremely important, maybe not for you guys but it is for us and smart women understand this so they can have a healthy marriage. You also have to follow the Islamic rules. The wife is not allowed to refuse sex from the husband and Allah who created us understands us humans far better than anyone else and there is a reason why he made this law to prevent men from cheating or other problems for that matter.
Delayed gratification? Just say you want a man with a low libido. He's most likely going to have a low testosterone level and be less manly. He may have other qualities you prefer from a man but he wont be handsome or muscular. You're not built for them nor do you deserve them.
