Op, the answer to your question will be a bit complicated. Definitely, some will be and some won't be.
It's just that we have to realise that marriage is for matured minds, not juveniles. This means before you go in, you must be sure of your problem solving skills. Be it sex, finance, in-laws etc., each marriage will have it's own peculiar challenge. If at the first sight of challenge, you take a short cut (e.g. going after other women because you are not getting enough sex), it brings to question your level of maturity before you married.
There is no problem without a solution; some solutions are however more difficult to find than others. The question will be, what do you value more between your ego and your marriage? The true test of a real man is his tenacity and determination when these kinds of situation arise. Be a man, stand your ground, and work with your partner till a solution is found.
For the guy blaming morality and saying sex is everything in marriage, I just wonder if you are married, and if that's the kind of standards you'll set for your children?

blame the moral code and the religious houses.
their intransigent view about pre-marital sex is destroying marriages. people get married to discover they are not sëxually compatible with their partners!

some work hard at making it work and sail through while others couldn't make it work no matter how hard they tried. marriage is a lifetime contract. it's imperative both parties get a taste of what is to come. there's a reason born again christians have the highest divorce rate...

maybe if they did their homework before marriage, things wouldn't be so bad for them!

Even before the emergence of Christianity and Islam in Nigeria, It is an honour for a woman and a pride to a man that the wife broke her virginity on their wedding night by the husband. It is a taboo to have loose virginity before marriage.
So give another excuse

A lot of married men are; unless they are getting extra from outside the home. The average male has a higher drive than his wife. She does all the housework, deals with the kids and is exhausted.. He is Hot, she is not. Teeth gnashing begins. He can manage and become a very sad married man or do what most men do

I sometimes wonder why house work should affect sex as if the man does not do anything in his place of work, if that is the case. If you turn it around and it is the wife that has a regular work, she would still give excuses.
Most wives do not exercise. Women that exercise have higher sex drive. Women should also learn to be romantic instead of waiting for the man to always do the move.
