As long as he isn’t asking you to sin, you have a responsibility to keep your husband sexually fulfilled. He kills the bugs (or gently lets them outside). He pays the bills. He takes care of your needs. So take care of his. Most men need sex. Once married, he’s only supposed to go to you for that. So don’t leave him hanging.
Now, obviously, if you tell your husband no, he needs to respect that. If a wife says no to sex and the husband continues on anyway, that’s rape. Rape should never be tolerated. But he has a thirst only you can quench, so quench it often. Don’t leave him wanting more.
There’s no excuse for cheating, but we open our husbands up to temptation when we deny them. Men (and many women) have sexual urges they need to express somewhere, and if denied by their spouse, they might find it elsewhere. That’s not okay, but it’s reality.
Sometimes sex is painful or you just don’t feel turned on. That’s where sacrificial love comes in. You do it not for your happiness, but for his. Smile, be an active participant, and think of it as a romantic gesture.
