So, according to your definition of "lust" there is not action needed (see definition provided from dictionary.com), but it is still sinful? I just don't think that could be the case.
I don't know, I was trying to get in the mind of a Biblical theist and failing as usual.
But I see your point, I don't know whether a lustful state of mind would be considered sinful, or just the action which results.
In any case I still have no idea why gay sex is a "sin" in the eyes of some theists.
