(CBS) "Glee" fans are gearing up for Tuesday night's controversial episode, which is titled "The First Time" and deals with just that. Two of the show's favorite couples will have sex for the first time - Finn and Rachel, and Kurt and Blaine.

Chris Colfer, who plays Kurt on the show, told Entertainment Weekly that he "absolutely expects" to hear from television watchdog groups about the scene, but that it was tastefully done.

"I think it's handled very sweetly and very emotionally," he said. "They're expecting this big, raunchy, suggestive, brainwashing storyline when really it's very sweet."

The Emmy-winner said he was initially apprehensive when he learned that Kurt and Blaine (Darren Criss) would lose their virginity to each other.

"It's funny, I always go into this instant panic state whenever they tell me about upcoming episodes because we always do so many delicate situations on the show," Colfer said. "But then I get the script and we shoot it and it's always handled so well that I never really had any reason to worry about it."

Finn (Cory Monteith) and Rachel (Lea Michele) will also have sex for the first time, but the episode won't just revolve about sex. Colfer told TVLine that there will also be a scene in a gay bar, the return of Karofsky (Max Adler) and the introduction of a new villain named Sebastian, who tries to take Blaine away from Kurt.

"I think Sebastian is one of those very promiscuous, driven characters that once they have their eyes on something they don't give up easily," Colfer said. "Let me just say this won't be the last time we'll see Sebastian try and steal Blaine."
