Most of us grew up getting advice about sex from our friends or the internet—which means that most of us probably think the 20 myths in this video are true. Or at least some of them are.
Which is where Dr. Adam Carroll, author of Don’t Put That There! And 69 Other Sex Myths Debunked, comes in. Dr. Carroll has collaborated with Mental Floss to make a video that looks at some misconceptions about sex—like are bigger breasts more sensitive and whether or not sex really is good exercise—and gives the answer to you straight.
So next time a friend or younger sibling or neighbor's kid comes out with something that you know just isn't true, point them in the direction of this video.
