Prostate play-- instructions, tips, pics, videos?

[Freya_Gin]

In other words, I'm interested in just about anything you know or have on the subject.

I did a search for prostate play on the forum and didn't come up with much beyond some people mentioning it. Does anyone here have more? I'd love to hear about your experiences involving this form of play. I've never gotten to do this to a sub myself and now I'm talking with someone who just happens to have a prostate handy who's also interested in this.

Edit: Shit, I accidentally posted this in the BDSM Cafe instead of BDSM Talk. Mods, can you move this, please? My apologies for the trouble.
