I agree with you there. Guys love looking at beautiful women. So what if you make a "yummy noise" about it?
Does your reaction to the commercial mean that you want your W to look like those women? No. Does it mean that you won't ML to your W because she doesn't look like those women? No. Does it make your W feel like a "lesser" woman? Maybe, but you've given her no reason to believe that - and that's her problem to deal with, not yours.
