Teacher shares students’ hilarious responses to their first sex ed lesson

But while most students are too busy having their minds totally blown by the “facts of life,” one class of US primary school students are asking all the hard-hitting - hilarious - questions.

Just have a looks a some of these gas questions about the birds and the bees:

One student was concerned about fatigue: “I know that intercoursing takes 24 hours. My question is how do you stay awake?” That's a good question...

While others couldn’t wrap their heads around “why” adults have sex, one refused to believe that their parents had ever been intimate.

The dumbfounded student said: “I’m sure my mother never had nothing to do with intercoursing … maybe my father?”

Getting confused between basic human biology and geography, another asked: “When the PENISE is put into the VIRGINIA, does it slide in quietly or click like a key in a lock?”

Unsurprisingly, the original tweet has received over 180,000 likes with many joking they’ll put these highly original questions on their “tombstones.”

One user said “click like a key in a lock got me WEEPING” while another added “aww these precious innocent babies! How cute and funny.”

A former middle school teacher also added her experience into the mix, saying that “every year I’d draw the female reproductive system on the board” and “every year there was one kid” who would yell out “Hey, that kind of looks like a reindeer!”

Oh... to be young again...
