Well, they didn't have Tinder, but I'm not so sure things were as different as you may think. Here's a pretty amusing letter Franklin wrote that may provide some insight into his thinking on the topic:
I've read it, but give more thought to points 3 and 4. Obviously people were sometimes having extramarital sex, but they were not freely admitting it and it could be truly scandalous (particularly for the woman) if someone learned of it.
Perhaps you would if you'd tried it :)
But really, doesn't this point boil down to: don't act like a sex addict, and avoid stirring up a bunch of drama?
