I was watching SEX TV one night (an interesting show that is made here in Toronto and is on regular TV saturday and sunday evenings)
Apparently the all time most popular sex instruction video is called "Bend over Boyfriend" It's made by a couple of lesbians and deals entirely with women using strap ons on their boyfriends.
Here's the link....

I'd order it, but it's like everything else, i have a million other things to spend my money on.
For the record, i have have tried the gf wearing the strap on routine and must admit i quite liked it, though doggie style was one of the roughest positions. Personally, reverse misionary was the way to go i found. Very pleasurable.
Another variation on a theme is for you to put a butt plug in her ass, and she puts one in your ass and you have intercourse in a missionary position.
When you finally have an orgasm, you can feel this strange pulsating inside your body. You have to try it to know what the hell i am talking about.
I had one girlfriend who would put anal beads in my ass as she was giving me head, then at the moment i came in her mouth, she would pull them out.
I just about went into convulsions with that little trick of hers.
