Considering previous debates about cheating, sex and mentality, this is the question. "Is it worth it?" In my country, for instance, 50 % of women cheat on their husbands, and that procent is excluding those that lied. And 60 % of men cheat on their wifes, (they probably lied less).
In my opinion, i wouldn't ever get married given these circumstances. I mean, there's nothing i hate more than a cheating women, especially a married one. I really love feminine beauty and stuff, i'm not trying to insult onest girls. But, common man, would you get married if your wife/husband is very likely to cheat on you?
