According to O'Reilly, one of the biggest myths we need to get over is that vibrators, porn, and masturbation will make you lose sensation.

You may have seen that Ran Gavrieli TED Talk about how porn makes men unable to get aroused by everyday scenarios, but O'Reilly says that's actually not true. In fact, one study found that men who watched porn were more sexually responsive and not at greater risk for erectile dysfunction. 

And if you're worried a vibrator would make you less sensitive down there, O'Reilly has reassuring news for you, too. "If you do feel a little numb right after a good battery-operated session, the feelings will likely subside in a few minutes," she said. "This numbness is similar to the way your body responds to sex or other repetitive actions and it is only temporary."
