I don't know about the Bible...
A few of us mentioned that "thought of doing someone" lasts just a split of a second. There are lots of researches about this subject, what is happening in all of us when we meet another person... but, I said already what I think and apparently it can be understood in different ways, which is not something I considered before I wrote what I wrote. However...
Women are much more selective than men are. As for me, I'm too selective and rarely meet a person that I'm attracted to that much that I would actually like to have sex with them. Me thinking would I "do" a person I meet have nothing to do with my behavior towards that person, or acting in that direction. I'm just simply aware of the fact that a certain person is that much attractive to me or not... in a fleeting moment- as bencountershaft mentioned.
For actually going in that direction and acting like that, there are much more criteria that a person needs to fulfill in order to make me want that for real. That's why I've never had a one night stand.
