What I remember is that Kurt and Blaine were in highschool still and they started a friends-with-benefits relationship. I think Kurt was shy and Blaine was possibly more experienced. And I remember that Kurt developed feelings for Blaine but knew Blaine didn't want a relationship.
And Blaine took Kurt to an adult shop to get some sex toys for them to try out and Kurt was asked on a date by the guy at the counter. Kurt ended up going in the date, and it made Blaine jealous and then Kurt was upset Because it turned out the guy only wanted to have sex with him, and wasn't interested in dating. I know Kurt and Blaine got together in the end. I can't remember if they were at dalton or Mckinely
And help would be very much appreciated!
