No, I think that's human nature.

ya i think that is just something they do unless its about your best friend

There is no such thing as mentally cheating. Fantasizing is normal. It becomes cheating when it takes place outside of his mind, in any way. However, if he is constantly fantasizing about other women, especially if they are people he actually knows, it's a big red flag that things are not well in your relationship.

As they say with love/commitment: 'It doesn't mean he never wants to sleep with another women ever again, it means he 'refrains' from doing so'. Fantasizing is not cheating in the least. It's 100% normal and fantasies are healthy in fact. Women have them too of course lol, no difference. I'm sure there has been a time when you saw a hot guy and thought a few naughty things ;)

I've had this conversation with my boyfriend and a few male friends, and they'v said the same thing - sometimes they do have fantasies, but it's onyl harmless, and it's 'a male thing' as they put it. I'm sure though, females are the same (we just dont admit it so freely!) we're only human right!!?? Just as long as it's only in your head and it's not real life, then it's definately not cheating! Look at it this way, what's better - a man to think dirty thoughts or to act and and cheat on you? I know what I'd rather!

personally i think it is just as bad as actually doing it...

No.

Many people, I know would say "no" but it depends on how it feels for you. Personally, I do not think or fantasize about other men.other that my boyfriend. If I do have fantasie's they involve him. I think i'm rare in this, but I am 100% monogamous in body and mind! Becuse of this though, I find it incredibly painful and so difficult to deal with the thought of my partner even thinking about other women. Recently I found out that my boyfriend of two years (who I live with) has been looking at porn. I can not stand the fact that he needs to fantasize about these other women to get himself off! This isn't helped by the fact that he doesn't really want to have much sex with me any more. He say's I'm beautiful and that he loves me, but still, I feel that something has been destroyed. I didn't think he was "one of those guys", you know. I feel very lost to be honest. Idealy I would love to be with a guy who is like me- monogomus and doesn't need other people (whether on a screen or otherwise) to arouse him. I am seeking therapy but I'm thinkin of leaving him all the same. In short, I do understand your insecurities and they are valid. You've a right to your standards and what you will or won't accept. Are there ANY porn free guy's out there?!

It says in the Bible the thought is as good as the deed.Meaning if you think it,you've done it,in Gods eyes.Question now becomes,do you believe in God?

After 20 years of marriage, you'll be thinking about anyone but your partner in bed ..... not say that they drift in thought 100% of the time, but fantasy is needed in relationships.

It is one thing to have a thought about a girl... it's quite another to entertain that thought. I can understand if a less-than-clean thought passes through his mind - that's human nature. But if he is not willing to cast that thought aside and focus on the beauty right in fron to him, what sort of character does he have? If your boyfriend can't control his mind out of devotion to you, what makes you think he will control his body? “Watch your thoughts, for they become words. Watch your words, for they become actions. Watch your actions, for they become habits. Watch your habits, for they become character. Watch your character, for it becomes your destiny.”
