Obviously everyone has different sensitivities, but if you cannot objectively identify sexism of both men and women in advertisements, yes you're a hypocrite.
Consider the context though. How were women treated a 100 years ago? How are they still treated? Feminism, etc.
I think you need a better model that takes this into consideration. Whether you like it or not for historic reasons there is greater sensitivity about sexism against women. I don't think rejecting this is being more objective, it's called trying to force an incomplete model onto reality.
