Should I tell my wife I am not a Firefighter?

We have been married for almost 6 years and I met her 2 years before that. While we were dating I heard her talk about the fireman that asked her out before and it bothered me because she said it every time we ped the fire station by her house. So I told her that I had become a fireman hoping to impress her and that's how she finally decided to marry me. My real job is at a lab and I am a tester for women's shampoo. Every shampoo that you have tried I had it on my body first. I am the lab rat so the testing is actually on me and I come home smelling like women everyday and tell my wife that I saved some kids and their mom gave me a big hug and I smell like women. Is now the best time to tell her what I really do for a living? Would you forgive me for such a huge lie if I was your husband?
