why did you link that? now i have to wash my brain out with soap.
Some soap: Everything you've seen or read about sex is false. It is an (growing) experience between the ones who have sex which can not be learned from a book or video.
Its the same as with everthing else on the internet (and of the internet for that matter) you have to always think critically, even if the content is wrong you can still learn. If you listen to Fox News for example you can learn alot about what technics the media uses, because Fox uses them totally obviously.
