Yes, I noticed that about Outlander, both the type of scene and that the most explicit one was Roger and Bree. I wonder if it's a negotiation by the stars or just a writing decision.

And I had long noticed the same about older British shows, though I must say that it's become very similar now with the U.S. when it comes to younger cast members. They are just all more attractive and casting for looks seems important. However what's still quite different is older actors. For starters, the older actors are more likely to look their age, and the older actors also seem more likely to be in romantic storylines. So there's still a greater sense of normality there.
