Why men cheat on women is an age-old question. The reasons why men cheat on women can be varied. Nevertheless, we have compiled a list of the top 10 reasons why both married and unmarried men cheat. Sometimes their reasons don't even involve you and it's simply an ego-based decision. Other times, reasons why men cheat can involve you and your relationship, or lack thereof.

So why do some men cheat in relationships? Almost all men know that cheating is wrong, yet many they still do it. Men will blame their reasons for cheating on their genes and their necessity to reproduce. However, aren't we suppose to be further evolved than a chimp? Shouldn't we be able to control our bodies through our minds and conscious decisions? Aparrently not always.

Here are the top 10 reasons why men cheat.

1. Because they had the option. The old saying ?men are only as faithful as their options? can sometimes ring true. Men don't get offered sex as often as women so when the opportunity does arise, it can be very difficult for them to turn it down.

2. It boosts their ego. Sometimes men don't feel like they are attractive to the opposite sex any more and when a woman shows some interest, not only does a man react, he may allow her to stroke his ego and more. There's nothing like the thrill of the chase to men on the hunt. When they are finally rewarded for their efforts, their egos swell even larger.

3. You grow apart. Maybe the two of you didn't have as much in common as you thought. He's met a woman who has more in common with him who loves football or plays golf. He may check out if he is compatible with her under the sheets also.

4. You argue a lot. Men will sometimes cheat to get away from an overly critical or argumentative partner. Who wants to be around someone who is constantly on them about something.

5. He's fallen out of love. Sometimes men become so comfortable in a relationship, they don't know how to get out. They may be staying in the relationship because of children or financial reasons. However, they feel like they are missing out on love and may seek it out elsewhere. In their mind, this is as close to win-win as they can get.

6. Your sex life sucks. If a man has a disinterested partner or isn't getting enough sex to fulfill him, there is a good chance he will have an affair. Just because you have a husband or boyfriend, does not mean you can stop trying. It takes a little bit of effort to keep your sex life from getting boring and non-existent. Some men cheat because they want to try new sexual things that their current partner will not try.

7. To get revenge. A man will sometimes cheat if he finds out his partner was cheating on him. How else is he supposed to heal those hurt feelings of his but through good old fashioned sex?

8. It's new, different and exciting. Some men get tired of having steak for dinner every night and want to try a hamburger. The same goes for sex with a woman. That's why men don't necessarily always cheat with women who are more attractive than their partners.

9. To see if they can get away with it. If a man has the attitude of ?what she doesn't know, won't hurt her,? he may cheat to see if he is sneaky and smart enough to get away with it. However, with all the advancement in surveillance spy ware, getting caught has now become easier than ever.

10. Because you have allowed it in the past. If you have forgiven a cheating man a couple of times, they are more than likely going to cheat again because they already know if they plead enough, you will forgive them.

Reasons why men cheat can be more complex than the above list or even be a combination of a few different reasons. Nevertheless, no reason is good enough reason to lie and be dishonest. After all, Karma can be a bitch.
