Well, my husband actually tried it once. I showed him the video from the Wayside of the girl shoving a small vibrator in a guy's penis.
I could not watch the whole thing, but he seemed intrigued.
I came home one day after being out, and he told me he tried it.
He said he kind of liked it, but that it would take some getting used to. He didn't tell me what he used, though. LOL I was actually very surprised he tried something like that.
