PARIS—There was the moment French President Emmanuel Macron greeted President Trump with a kiss on both cheeks, French-style, prompting a Fox News commentator to explain that in France, that kind of thing is normal, even for men. There was the moment Trump pretended to brush dandruff off Macron’s shoulder during an Oval Office photo shoot. There was the unforgettable, amused, “I-can’t-believe-this-is-happening” look on Macron’s face when Trump said the Iran deal was terrible, end of story. There was the press conference where Trump, in television game-show-host mode, said he might withdraw from the Iran deal, or might not and instead offer “a very large deal, maybe deal, maybe not,” and anyway stay tuned for his May 12 decision deadline. There was the weird photo of the two presidential couples planting a tree, and Melania Trump’s white, wide-brimmed hat.

"Your husband will want sex way more than you do," advises Elizabeth of the blog Warrior Wives in a post called "Wifey Sex Confessions."

"God just made him to think about sex more than you. ... Never demean this about him. Never laugh at him or make fun of him. Accept it as a difference."

Accept it as a difference. It may sound like so much cliched marital advice, but this is a much-discussed idea about sexuality in the evangelical Christian community: Men and women are different.
