As for telling lies.........
I've also started a habit of using reverse psychology. Just tell her every so often some lies/truths. I've actually started telling her now at least 2-3 times a week that I went and got a happy ending massage or something similar, in a joke kinda way when in actual fact that you've done nothing but work. Or if she asks "how was your day?" throw in some random answers like "yeah it was good, had lunch with a pornstar called Tiffany!" After a while, she'll just hear BS, while in actual fact, they are truths. I try to keep my lies stories revolving around the same imaginary names, like I frequent a masseur called Angel or a stripper name Amber, or hooker called Tiffany. So then everytime she hears these names, she'll immediately think of you BS-ing her again. This takes a bit of time.....
I do this as well, but I think it really depends on the SO and her sense of humor.
My SO has never had any trust issues before, so she is really relaxing with me. But if a SO has been cheated on before, then they might not be so easy going.
I think common sense just has to prevail all the time and things should be fine.
Just don't poon around with family and friends. I don't know what some brothers are thinking when they go and play with this type of fire.
Also, I knew someone who went and blew over 15000 US dollars on a business trip, supposedly at the bars. No SO is dumb enough to believe that.
