TBF, WITH BLAINE THEY HAD HIM HAVE SEX WITH SOMEONE ELSE BECAUSE IT WAS LOL CHEATING, AND THEN WITH KAROFSKY YOU CAN'T RLY GET AWAY WITH HAVING THEM LIVE TOGETHER WITHOUT THE ASSUMPTION THAT THEY'RE HAVING SEX. WITH PAIL IT WAS FAR MOAR AMBIGUOUS BECAUSE PAIL'S LAST APPEARANCE WAS THEM KIND OF DISCUSSING THE IDEA OF THEM BEING MOAR SRS. IDT THEY HAD SEX, BUT IT'S A WEIRD DISCUSSION BECAUSE SO MUCH OF IT IS WRAPPED UP IN GLEE'S LOL DOUBLE STANDARDS. RACHEL HAVING SEX WITH BROADY WAS KIND OF A BIG DEAL BUT WE'RE JUST LEFT TO ASSUME WITH KURT AND PAIL AND EVEN SANTANA AND DANI.
