Glee Season 5 Episode 16 delved into some serious topics this week.

To wit: the boys got tested for STDs, prompting Artie to tell his sexual partners, while Kurt and Blaine went through some relationship issues after Blaine put on his "freshman 15" due to his love of cronuts.

Elsewhere, Mercedes admitted to Sam that she's still a virgin and she isn't sure when she'll ever be ready for sex. 

Like we said: serious stuff.

To see how Sam reacted and to learn who Mercedes went to for advice, watch Glee online now:
