Can you say, "biologically predisposed"? It's true, guys; the verdict is in, and it turns out that we are instinctively the hunters of the species. Scientific research (conducted by men and women) has concluded that -- are you ready for this one? -- we are all animals.

According to The Myth of Monogamy: Fidelity and Infidelity in Animals and People , we've evolved beyond the majority of primal instincts that rule our actions, but we still act according to our instincts, sexual and otherwise.

That said, regardless of what even the biggest player has to say about the luxuries of running around town planting his proverbial seed, there's nothing better than knowing we have a loved one waiting for us.
Examine Your Relationship
But even with the feeling of security and comfort that a great girlfriend provides, many men still can't seem to remain faithful. Is there a problem with the relationship? Is the "other" woman too hot to refuse? Has your girlfriend changed? Or are you just plain bored? Let's take a look at the different issues that plague relationships and the dating game, which may lead to your desire to cheat.

1. Your girlfriend has gone downhill
Whether she's been neglecting you, is an incessant nag, or simply isn't ready to commit, that woman in your office building is suddenly a more appealing option.

Solution: If you feel like she's been neglecting you, tell her so. Based on her response (or lack thereof), it might be time to renegotiate your contract, so to speak.

2. You need to prove that you "still got it"
For some reason, having a great girlfriend sometimes isn't enough; we need to prove that other women think we're great. And so, in our efforts to prove that we can still shake 'em down, we attempt to get it on with someone other than her.

Solution: Role-play with your girl, dude. Chances are you won't be happy when you lose your lady because you felt this incredible need to tap the ass of a babe just to feel better.

3. You think the grass is greener on the other side
Men tend to think that if we landed the woman we're with, we can do even better. It's the BBD (Bigger, Better Deal) syndrome and it can sometimes cloud our judgment, especially when a hot blonde in a tight skirt looks our way.

Solution: If you want to be single, be single. If you want to be in a relationship, then do so. If your desire to be with other women overrides your happiness with the one you're with, then maybe it's time to let her go.

4. You (seemingly) get more attention from other women
Many men don't realize that the very security they feel in their current relationships is what gives them the air of confidence that other women find attractive. Maybe the fact that you're currently attached prevents you from acting desperate, or makes you look like more of a challenge to other ladies.

Solution: Thrive on the attention and appreciate it, but don't let it get to your ego too much. After all, you're getting all these looks because you're in a relationship. Tell your woman about some of the other ladies that check you out and make a joke of it.

More reasons you might stray...



5. You become part of a woman's plan
Most women are extremely competitive. If another woman sees you with a lady that she considers less attractive, she'll jump at the opportunity to "show her up." Most of the time, it's just a game that ends once she's proven her point. If you respond to her in even the slightest way, she'll feel that she won.

Solution: If you're happy with your current girl, don't let the hot chick manipulate you. Instead, reject her flat out and although she'll likely want you even more, you can feel good about the fact that you rejected a hot one.

6. You think you don't deserve her
You may sometimes feel like you don't deserve her. More often than not, that means you've been unfaithful -- whatever your definition of "unfaithful" might be -- and feel guilty about it. Or perhaps she's simply advancing at a rate too quick for you.

Solution: You can't ever begin to feel insecure in a relationship. If you think she's too good for you, figure out why. If you can't handle the guilt of something you've done wrong, fess up or let go. If you think she's smarter than you or hotter than you, do your best to keep up, or even appreciate the fact that she's so sexy or knowledgeable.

7. Your girl doesn't appreciate you
She's begun to take you for granted and all the gifts you buy her are now "expected." Because she criticizes you more often than she compliments you, when that hot babe in the corner cubicle notices how "sweet" you are, you suddenly feel good about yourself and want to spend more time around her. Before you know it, you're constantly at odds with your girl and getting along swimmingly with the "other" woman.

Solution: Tell her everything. Tell her that she's taking advantage of your generosity and is constantly complaining. Tell her that you're not going to put up with her behavior and if she doesn't change, you'll walk. And if she bitches even more, follow through.

Maybe she let herself go..


8. She let herself go
If she isn't as attractive as she once was, it's natural that your eye may start to wander. If you've done the same, then you likely have no right to complain. But if you've maintained your appearance and for some reason or other, she's begun to make whales look anorexic, chances are that you may be tempted to step out on the relationship.

Solution: You have three choices here: you can leave her, cheat on her, or you can tell her that it's time to get her butt into gear and start taking better care of herself by working out with you.

9. You're afraid of commitment
Sometimes the thought of getting married and having children is too much for even the most mature guy to take and, in effect, he ends up in the arms of another woman.

Solution: If you end up feeling this way, rather than run in the other direction, face the issue head-on and let your girl know that you may not be ready to delve into marriage and kids so soon. If she can't accept it, then perhaps you'd be better off single and free to step.
It's Our Instinct
So why are we prone to cheat? Instincts. While women refer to theirs as intuition, men's instincts are considered to be beyond our control and are mostly hormone-driven. Now don't think for a second that this a valid excuse to stray in the eyes of the ladies.

No woman will watch as you sift through journals of DNA tests of monogamous animals. Our biological predisposition still isn't a reason to cheat -- we are capable of making a conscious effort to be faithful.
Cheating Hearts
Unfortunately, sometimes she may not even be the problem. Be honest with yourself first, and then with her. Don't try to be someone you're not because if she fell in love with the guy you're pretending to be, you'll have to act that way through the entire relationship. If she doesn't like who you are, then you don't need to cheat on her -- you need to break up with her.
