Is having sex with another guy while having a boyfriend considered as cheating?

Different relationships have different definitions of cheating, but, as a general rule, undeniably yes, sex outside of your relationship is, nine times out of ten, considered cheating, and the only time it is not considered cheating is if BOTH partners agree to an open relationship.

I do not know if this question is referring specifically to you and your relationships, but if it is, I'm assuming that you and your boyfriend are in the typical monogamous relationship, rather than the atypical polygamous relationship. In that case, straying outside that monogamous commitment is definitely cheating, and can hurt the other person. Whether it's a guy sleeping with another girl, a girl sleeping with another guy, a guy sleeping with another guy or a girl sleeping with another girl, sex outside of the relationship is what modern society colloquially calls "cheating." Other names for it include infidelity, straying, adultery, betrayal, and having an affair (though admittedly, the latter one assumes a second relationship which implies having sex out of the relationship at least more than once).

I hope that cleared up any confusion on the subject. Nine times out of ten, there is no wiggle room. It's infidelity. The tenth time out of ten occurs in polygamous or open relationships.

MOG! I never heard of a person who wouldn't freak out and throw a violent fit just from hearing someone ask a question like this. So yes I believe it is.

It is, but I'm okay with it.

Yeah, I'm pretty sure that when you have a bf, you shouldn't sleep, make out or show any sign of physical affection with anyone but your boyfriend.

Unless you guys are swingers than yes

*looks at Cinder's answer* There's your answer :3

not really,if u only had sex with this dude and never saw him again,then no.it was just a 1night stand.

the fact u have 2 ask is sad enough! u clearly dont care about ur bf enough 2 just keep urself 4 only him.

Well as you already know, I don't think it's cheating if the two people aren't married. I mean when it's just a boyfriend/girlfriend relationship they don't own each other so I think it's perfectly fine.

You know that in my past I've been known to play a few guys, I see nothing wrong with that. I'm not married to them, I don't own them, they don't own me.

Yes,i consider it as cheating.

noo shit sherlockk!! you think its opkkk to fuck some guy and leave you man hanging damn your a bitchh i would dumpp your asss!!!!!!!!!!!

Yes, it is cheating. What if you become pregnat and then he finds out? Huh? He will probably break up with you if the info leaks. It is considered cheating in my book. Only have sex with one guy.
