Where to buy "mature" music videos for Itunes

A while ago, I asked for recommendations for mature themed music videos. I found that many of these videos were not available at the Itunes store. Are these just not available or is it possible that the Itunes store does not carry mature material? If that’s the case, is there any other way I can get such videos and put them in Itunes?

If you can find them on YouTube you can use the converter at vixy.net to convert them to mp4 and load them on your ipod that way.

Thanks for the suggestion, but I’m looking to buy them legitimately.

It’s not illegal as far as I know.

How could it not be illegal?

Do I have to say this again? I want to buy them from a licensed source.
