Vaginal Weightlifting?

So I was on YouTube watching Buzzfeed and saw a video of a woman who does vaginal weightlifting and she spoke about how when you strengthen your vaginal muscles it increases your labido and you are guaranteed to have an orgasm. She said that when your muscles are weak you can often feel very numb and most women never experience a vaginal orgasm due to weak vaginal muscles. I was so shocked when I saw this because I have never had a vaginal orgasm! So I want to try it! Please leave your comments!
