Hi,
Personally I wouldn't trust someone who has the characteristics Dr. Paul describes. There may be many reasons why you haven't cheated. On the other hand what do you consider cheating? Maybe we should start from there.
In any case, I have found relationships with people with characteristics described in this article, very unsatisfying to say the least.
I have also behaved in a similar manner so I have to agree with Dr Paul, just by looking at myself.
