Regardless of sex, it happens to the best of us. The only difference is the reaction of the two sexes when it comes to being cheated on. The majority of men are willing to look past an affair committed against them and some even want to save their relationship. The story is a bit different for women. If you are currently dating a guy who has a history with an unfaithful partner, you are dealing with someone who may have some serious trust issues. That alone is kind of hard to work around- he is easily wary about dating women because of his experience.
