#Edit: Linked to OP's pose about adamantium

A potentially controversial take, but I don't think the Honda Oddysey scene is necessarily meant to depict sex, but it is definitely meant to depict intimacy or, at least, vulnerability.

I know equating the motions of the fight to sexual encounter is fun (I do that, too), but I think in the process of it, the meaning of the scene and the fight itself is often overlooked. Regardless of whether or not those two got their dicks hard during the fight, I think what was most necessary for them was just finally finding someone who's their equal who can match them blow for blow — especially for Logan.

Someone pointed out that Wade's katanas are made of adamantium, the very steel that builds up Logan's bones and therefore, his claws & primary weapon. Healing regeneration and virtual immortality aside, they are also evenly matched when it comes to their offensive. They are quite literally matching up to each other. Finally, this is someone they can hurt and not only that, someone they can hurt with their own violence, and someone who will survive it.

There is vulnerability in the violence, intimacy in the enduring of it. It isn't everyday — or perhaps, it hasn't even happened at all — that the two of them encounter someone who can match up to them. All their violent and gorey instincts, poured out into one fight and channeled towards the one person in the (multiverse) universe who can take it.

So, yes, it's probably like sex to them. But not because of the motions of it, but because of what it means to them.
