Will any man cheat if given the opportunity?

Any man left alone with a tea cosy will put it on his head.

Same here though, I have kissed a guy who has had a girlfriend and stuff but they're just clearly not as in love as they probably think they are. Maybe the guy who tried to kiss you was incredibly drunk and didn't intentionally mean it.
There are also loads of guys I know that have had the chance to cheat and completely rejected the girl because they know they're in a relationship with someone they love.

Cheating while drunk definitely still counts as cheating. That's why I dont drink too much when Im out compared to my single friends; not worth making stupid mistakes. Am still quite young but i hope this philosophy wont change as I age.

Yes, he was drunk and didn't intentionally mean it, that's the point I am trying to make. He would never go out of his way to cheat, but still would have in that situation. Cheating while you are drunk still counts as cheating.

Also, regarding your last sentence, of course most decent guys will reject girls when they are in a relationship 9 times out of 10, but are you telling me they don't have the potential to ever cheat in any situation? Don't forget, when guys are in their 20s, relationships are still a relatively new thing to them and they haven't had as much time to be unfaithful.

So if you did happen to accidentally get too drunk one night you think you could potentially cheat? I think a lot of guys are like you, but they don't realise it. They genuinely think they would never cheat regardless of the situation. Some of them probably don't realise they would ever cheat until it's actually happened.

There are obviously men who will go out of their way to cheat on their partner. They might come on to girls on nights out and have one night stands, or they might flirt with girls they know with the intention of it leading to something more.
And there are obviously many men who will never do any of the things I just mentioned. They genuinely want to be faithful to their partner and are against cheating. However, do you think all these men potential will cheat in certain situations? There are many men who have been married for years and years and have been faithful, but are these men who have not had many opportunities to cheat? Many guys, once they get into a serious relationship, don't tend to go out much and socialise with lots of women once they have finished university and are working full time. Most of the guys I know at work only really go for nights out with their partner there, and if they go out with just their friends, it's very rarely a big night out where there are loads of women there.
The main reason I am asking is because recently, a married guy at work, who I am friends with, tried to kiss me when we were both drunk on a night out. This guy is one of the nicest guys and is known to really love his wife. I didn't kiss him, but if I had, I'm sure it could have lead to more if I had wanted it to. Similar things have happened to me with a few other guys in the past, who were all also the stereotypical nice guy would never cheat type. These guys never go out much since they have been in serious relationships, so I believe they don't do this kind of thing often. So that got me thinking, will all men cheat in certain situations?

By the way, the reason I am asking about men and not women is because I am female so it interests me more, I am not trying to be offensive.

The key is not getting that drunk to the point where you arent in control of yourself. I've gone out countless times and never ended up that drunk.

But hypothetically, if I got drunk enough and somehow a random girl was with me in a hotel room and unzipping my pants, then yeah I would have sex with her. But I cant give consent when Im that drunk, so technically I've been raped. And being raped is not cheating.

Of course you can have sex when really drunk and it not be rape. People often give consent when they are drunk. What gave the idea that it is not possible?

You cant give proper consent when intoxicated. Thats the entire point tho.
