Hey man just because you got a threesome doesn’t mean its common.
Spontaneous group happens in real life -> I agree.
All the time -> I don’t agree
There are people who seek it out
But that doesn’t mean they get it “all the time”
Unfortunately the difference between those two types of people defines the lens through which you define a “naive” person.
And your lens is too much caliberated to view every encounter as an opportunity even if you don’t know whether the OP is actually into it or not, thus projecting your expectations into the scenario.
or they just place a block of cheese near by as a shelf or counterbalance for the chopping board for the actual ingredients.
