Actually you may be right. A guy I clicked with years ago liked playing this for me. We were really different tho, maybe we were duals.
Him: I love the opera
Me: I don't really like the opera lol
Him: I drive fast
Me: I don't drive fast....
Him: I like lots of sex partners
Me: I like just one at a time
Him: (told me what to do)
Me: (allowed that, but argued and challenged his reasonings a lot)
It probably was pretty complementary but Idk, I think we both wanted something a tad more similar. We didn't even really meet irl though, it was just over the phone.
