( EW.com ) -- Last winter on the set of the show 's massive post-Super Bowl episode , `` Glee '' co-creator Ryan Murphy told EW that he wanted the gay teenage relationship between Kurt ( Chris Colfer ) and Blaine ( Darren Criss ) to be just as complicated as any of the show 's heterosexual romances . Now he 's making good on his word : Tuesday 's episode of the Fox hit , `` The First Time , '' finds not only Rachel ( Lea Michele ) and Finn ( Cory Monteith ) having sex with each other for the first time , but -- in a groundbreaking move for an 8 p.m. series -- McKinley High 's gay couple doing the same . ( Warning : SPOILERS ahead ! ) `` We were talking about it [ in the writers ' room ] like , 'Why should n't [ Kurt and Blaine ] lose their virginity at the same time ? ' '' Murphy tells EW exclusively . `` Everybody has seen a straight couple losing their virginity , but has anyone dovetailed the gay and straight stories together and given them equal weight ? That seemed like an exciting choice and a new thing . '' According to Murphy , the four actors ' only worry was that they look good in the love scenes : `` The first thing they all said was 'Do we have to go on diets ? ' '' Originally , when there was talk this past summer of a `` Glee '' spin-off , the thought was that Rachel would lose her virginity after moving to New York . Says Murphy , `` Some of the women in the [ writer 's ] room thought it was crazy and thought we should really give that moment this year to Finn . '' The `` Glee '' co-creator also reveals that network Fox expressed no concern over the episode 's potentially polarizing subject matter -- though the Parents Television Council issued a statement Tuesday condemning the episode : `` The fact that 'Glee ' intends to ... celebrate children having sex is reprehensible . The gender of the high school characters involved is irrelevant . '' Murphy , who is n't surprised by the controversy , is staying focused on the bigger picture : In a year when bullying and teen suicides have grabbed headlines , he 's hopeful that Kurt and Blaine 's romance will continue to deliver a positive message to `` Glee 's '' audience . `` I think what it says to a lot of young gay people who are confused and ashamed is that you can get love and are worthy of love . '' `` Glee '' : Get the latest news , photos , and more . Viewers also saw the return of Kurt 's bully , Karofsky ( Max Adler ) in Tuesday 's episode . Surprisingly , Murphy says he gets a lot of comments , particularly from gay men , asking for a Kurt/Karofsky romance . Says Murphy , `` We 're going to write something about it . I do think the reason why he attacked Kurt so viciously is he he had all these feelings that he did n't know what to do with . I am interested in that , like what happens if he finally got to express that in the right way . '' See full article at EW.com .
