Cheating

I don't believe it's the sex which is wrong in cheating, for me it's the deception. If a couple are happy and willing to have an open realtionship then to me that's not really cheating because both parties are fully aware of what is going on. I think it's wrong when a decision has been taken by the couple not to have relations outside of their marriage/relationship but one half of that marriage breaks that mutual agreement.
Also for me cheating doesn't necessarily have to involve sex, it can include anything that involves emotions being placed on a person other than the one you are in a relationship with while not disclosing it to your partner (if that makes sense! )
All in all, I just think it's wrong to mis-lead someone or hurt them by doing something which you know is not accepted in your particular relationship

What abt the point* that you cannot control who you have feelings for, hence short of physical relations, one cannot "cheat"?

*this may not represent my real views.

I think there is a difference between fancying or liking someone else and actually doing anything about it To me, I know that my bf will and does fancy other girls, it's just a fact of life. However, for that to move onto something else he would have to spend quality time with someone else behind my back. Also, if my bf was seeing someone he fancied while not telling me or whilst telling me that there was no-one else for him etc, then I would see that as him deceiving me by lying about his feelings for someone else.
You're right, you cannot control who you have feelings for but I believe those initial feelings are purely physical (which can't be helped) but for things to progress to 'true' feelings you'd need to spend time with them in a more intimate way

Yes, I to think one has a degree of control. But just as a person would get tired of coke everyday, and desire a Red Bull, so one could get tired of a gf and desire another woman for a change.

No?

No No matter how much you'd like to try a Red Bull if you've promised that you'll only drink coke then that's what you should do If however, you're really bored of coke then by all means put it back on the shelf but don't try to drink both at the same time, let the coke go before picking up the Red Bull

But Red Bull and Coke...is a mind blowing combo.
