Well, they say 'knowledge is power,' and I think sex is a great example of that. You really do have to have knowledge to make it good for yourself but even more so for your partner, but too few seek the knowledge they need. And I don't think you can ever really stop learning when it comes to sex. There's always something you don't know, but no one can really know everything. Hell, there's probably new things yet to be discovered by anyone, and things that have been lost to time that must be discovered again.
