ABC Family's The Fosters made history on Monday with its broadcast of a same-sex kiss.

On the show, now in its second season, Lena (played by Sherri Saum) and Stef (Teri Polo) are two working moms coping with raising five children, including the recent addition of a wayward teenage girl.

Jude (Hayden Byerly) is the youngest son in the family at 14. Connor (Gavin MacIntosh) came to Jude's rescue when he was being bullied. On Monday's episode, Jude confronts Connor about their relationship and Connor responds by kissing Jude. It is believed to be the youngest same-sex kiss in television history.

“This story line is important in so many ways,” MacIntosh told “It's been eye opening about how many kids struggle with feeling 'OK' about questioning their sexuality.”

“Just being 13 is difficult enough, going through physical and emotional changes, then if you add in not being sure about if you like boys or girls, and society telling you that you should be a certain way – I can see why so many kids are struggling.”

He added that he was “proud” of his role on the show.
