相信姑娘们都对男人的身体出轨困扰不已，在此，我试图用5个简单的原因来解释这一头疼的问题。女人不理解男人怎么可以劈腿成性，这并不意味着每个女人都会去立贞洁牌坊，但女性在跟非男友的男性上床前一定是渴望更深入的亲密了解而非仅为生理快感（基于一定的爱恋）。但男人可以将性，爱分离，所以他们可以和一个认识几分钟的女人上床，这，正是他们出轨的第一个原因。
1. Just because its been offered to us.
1. 送上门的猎物不要白不要
Lets face it, just like Chris rock said, “It's almost impossible for a guy to turn down free p***y. If it's chasing us, we can't run that fast.” If you are a girl, that means that you have been offered sex every day since you were 12; every guy that's being nice to you is just offering sex. For most guys (unless you are super famous), it doesn't happen everyday; we aren't offered sex that often. It just seems like a wasted opportunity when a girl says no. Men don't know when a chance like this will ever come again, and if you think about it, it's partially the girl's fault. (Ok, ok. That wasn't fair. I'll take that back.)
面对现实吧，正如 Chris rock所说：“没有哪个男人会拒绝送上门的姑娘 。我们无力抗拒这样的诱惑。”当一个姑娘长到12岁，就意味着她可以承受鱼水之欢了（要不要这么早熟啊...TT），所以这之后每一个对你殷勤献媚的男人都是为了把你骗上床。对于大多数男性（除非你是万人迷），并不会经常遭遇送上门的艳遇。这就意味着，当一个姑娘拒绝他的上床请求时，便浪费了这男人一次宝贵机会，鬼才知道下一次机会在哪里，这么说起来，好像是女孩子的错喽~（好吧好吧，这么说实在是太不公平的，我们还是言归正传。）
2. Insecurity and trust issues
2.内心不安和信任问题
The insecurity and trust issues are major reasons why a guy constantly cheats on his girlfriend, wife, fiance, whatever. It could be a problem they had from the past relationship or they just don't feel like they are good looking enough for the girl. This is the number two reason why a guy will cheat on a girl.
内心的不安定和不信任感可以让一个男人不断背叛自己的女友，妻子或者未婚妻。这种潜在的信任危机可能源于他之前失败的感情经历 或 他并不认为你是他的真命天女（这个理由要有多操蛋啊~TT）。这是男人劈腿的第二个原因。
3. Not being fulfilled by their girlfriends.
3. 女友无法满足他们
This works both ways. If a girl is not doing the things that the guy likes sexually then they will go out and find somebody that will. So you ask, how come they just can't break up with them and find somebody who will? I mean, think about it this way: Most times it's the good girl that doesn't want to do the freaky things the guy wants. Now other things might just be perfect or damn near close, something as simple as she has a car or makes more money.
此条男女适用。如果某女无法满足自己男人的某种性趣爱好，这家伙可能会出去找乐子以满足自己（好禽兽的原因啊~~~彻底的下半身思考，有木有）。这时，你可能要问，那他们干吗不直接和这个姑娘分手另觅姘头？好吧，但很多时候，一个好姑娘往往无法说服自己极尽风骚地去取悦男人，大老爷们总不能因为此就去找个婊子了此余生啊~而另一个简单的原因则是，这个好姑娘有自己的车或者收入不菲，其实男人也是很现实的啊~
4. She told you that she cheated before
4. 女友不忠在先（为毛男人出个轨尽给女人找问题？这作者男权主义啊...吐槽下，继续翻...）
You ever heard of the phrase, “Once a cheater always a cheater?” Well that's kinda how it works when a guy feels as though his girlfriend has the potential to cheat on him. That could trigger him to cheat first just so that he could have the upper hand. If he finds out that the girl has cheated on him, it wouldn't bother him as much because he has already done his dirt.
你大概听过“一朝为贼，终生为贼”。当一个男人觉得自己的女友具有潜在背叛他的可能性时，这句“名言”就会开始困扰他。这种不安的情绪会驱使他先出轨为强（尼玛啊，都木有证实就骚动了，根本就是借口...吐槽完毕，请大家忽略）。这样，如果他真的发现女友劈腿，心理上就不会太过纠结痛苦，因为这龌龊的勾当已被他抢了先手。
5. Have your cake and eat it too
5. 鱼与熊掌不可兼得（大概是要说长得又帅，又浪漫，技巧又好的男人还非常专一的男人只能是火星人吧...）
I never really understood that phrase but I figured I would use a cliché. All I am trying to say is that, some guys just can't sleep with one girl so ladies if you find yourself with a guy that cheats on you, chances are he will never change. He will always cheat on you and everybody else that he will be with. Something in them will never allow them to be faithful. Its just in their system to go out and cheat on their girl. They can't be single, but they like to cheat also.
陈年老词或许让你们厌烦，但我说了这么多，只是想告诉你们，有些男人吧，他确实没办法只踏实地睡你一个人，所以，如果哪天你发现他出轨了，就不要妄想他以后能和你安心过日子，这并不是说你缺乏魅力，而是他骨子里无法对任何女人忠诚，如同狗改不了吃屎，问题不是主人给予的食物而是秉性所致（不过坏男人还真是从来不缺女人啊~）。
PS 欢迎大家一起吐槽...~
