Marriage is just a ritual or commitment to support each other. It does not say anywhere that woman body belong only to that man.
Tying a piece of thread or a wearing a ring does not conclude that man to do anything whether she likes or not. It is all human created.  Every woman has right over her body. She will decide to whom she can give her body. Cheating/cuckoldry/extr marital affar It all depends on how that man takes it. The same is applicable to man as well. The body is just a piece of flesh that will decay slowly as age grows and going to go inside the ground or in fire. Till the time life goes, each can decide how and with whom they wanted to live happily.
But commitment remains the same. Helping each other and nursing the kids born to them and help them grow as a good person in the society is their responsibility. Sex is not life. It just a bodily need for each other for few minutes or hours. It cannot last for life. Too much of anything will not be liked after some time. The same is applicable in the sex life also. Only the true love will be till the end of life. It depends whether the couple have it between them throughout their life.

If your marriage life is not good just divorce and marry the person you like, That is called Life Ethics.
