I've seen Youtube video by a (male) psychologist that dealt with exactly this topic. He claimed that respect and sexualisation cannot really co-exist, a man can either respect a woman, or want to fuck her brains out, but not both, at the same time. With a wife, he maybe needs to compartmentalise, so he can put aside the respect when he wants to let loose sexually.
However he also argues there is a difference between men and women in what they mean by respect. What women call "respect" is actually the absence of disrespect, which is not what men mean by respect. For men, you only "respect" someone who is extraordinary, or above you in some way. You don't "respect" an equal.
To put it another way, female "respect" is the human dignity and consideration that maybe everyone is entitled to, by default. Male "respect" is admiration for a superior being, who is exceptional in some way, and so does not apply to most people.
He sees it as problematic that boys are taught by their mothers to "respect" women, as they may misunderstand the message, and think it means they must suppress their sexuality at all times when dealing with women, even in a dating context where that might be highly counter-productive. The reason boys are confused is because in all situations where "respect" in the male sense occurs, sexual interest would be highly inappropriate. For example, respect for a teacher, respect for your boss, respect for a senior officer in the military, respect for a judge, respect for a politician, respect for the dead person at a funeral, etc.
