No Hanksy-panky: the curiously sexless Tom Hanks

In Tom Hanks's new film, A Hologram for the King, he has sex with a woman. Get in, my son! It's an actual sex scene with boobs and everything. As the United Kingdom's foremost Hanksologist, it occurred to me that I hadn't seen this before. (A proper Hanks sex scene, I mean: I've definitely seen boobs. No, you don't know her; it was when I was on holiday.) So why is this?
