Are you ready? The new season of Girls returns to HBO on Sunday, February 21, and there is a lot going on. "I think everyone is growing up a little bit, or trying to, but it's Girls so it never goes that well," the show's executive producer, Jenni Konnersaid in an interview with HuffPost Live on Tuesday, February 16.

Marnie (Allison Williams) is getting married, but the show is also breaking more boundaries in season 5 by exploring the subject of masturbation. 

While Jemima Kirke (Jessa), who's featured in the scene, knew she was headed into headline-making territory because "I know that [it's groundbreaking] when it's something we get really excited about doing," Konner said that she's kind of clueless about which scenes will cause a stir.

"I am famous for never being able to guess what will be shocking," she admitted. "I'm always wrong."

Because the show does feature more graphic moments than viewers would see on network TV, Jake Lacy (who plays Lena Dunham's love interest, Fran) explained that the sex scenes are carefully choreographed. 

"It's handled incredibly professionally and delicately and that comes from the top, with Jenni and Lena from the get, saying like, 'Here's what's on the page, here's what the nudity is, here's how we're going to shoot it, here's who's in the room," he said. "There's no freewheeling element, to like, 'Take it off if you want to, show what you can, let's just have fun.' That's not really how this goes down."

But he did admit that one of his upcoming love scenes with Dunham gets "pretty steamy," and joked that it was not unlike the hot and heavy scene between Leonardo DiCaprio and Kate Winslet in Titanic: "A piece of glass rose out of nowhere and my hand slid down it."

Girls returns to HBO on Sunday, February 21, at 10 p.m. EST.
