I guess it raises some red flags that your husband is practicing these "little white lies." However, if you have already been trying to talk to him about it and he is not receptive, I don't know what to suggest. I guess you could tell him that someone online agrees with your position, but I'm skeptical that he'd be persuaded by that.
Dishonesty always raises some red flags, although it helps if your husband has a plan to end the lying, and follows through with that plan. In the meantime, you just have to decide what you can live with, and for how long. It doesn't sound like your husband is willing to bend his position, so you will have to decide if you can tolerate that behavior.
For what it's worth, I don't think you're "just acting all hormonal." It's perfectly reasonable for you to be concerned about lying. As I said though, it's just your own actions that you have control over, as he chooses his actions.
Love means never having to say, "Put down that meat cleaver!"
