If you're seriously itching to get it on with someone else, then either convince your partner to be in an open relationship, or break up with your partner before going after other people. SIMPLE.

Cheating is rarely just the physical act alone. It requires deception, lying to someone you claim to love, breaking trust, and completely dishonoring the relationship. If that's not "bad" then I don't know what is.
I don't think I can add much to what Miriel said on it. A monogamous relationship is expected to be just that. If you want something else, then find a partner who's okay with something else. But given that most of our society is structured around the idea of monogamy, it's pretty reasonable for people to presume that's part of the deal in a marriage.

The problem isn't that people make a big deal out of things. It's that people don't know how to deal with big deals. Whilst nothing as large as cheating occurred, my grandparents had their share of rough times, and they stayed together happily until my grandad bought the farm. My grandma still loves him to this day, more than ten years later. It's a factor of willpower and the capacity to figure things out, not a factor of the ability to change how big a deal something is.
