Well, you can’t really go wrong with a good adjustable-speed bullet/egg vibe. They’re pretty cheap, and they’re quite versatile. You can use them in the traditional manner, insert them, put them into sleeves or cockrings, you name it. Make sure it’s an adjustable-speed one, though, the two-speed ones tend to be set a little too high to enjoy for very long.
I’m also really fond of massage stuff. I’ve got this mitt I bought at a party a few years ago that has all these little “fingers” on it…you’ll take it out of my bedroom when you pry it from my cold, dead, sticky hand. It’s also wonderful for non-sexual massage of the back, neck, and feet. When I was waiting tables, a foot-rub with that thing after a 12-hour shift was “who needs a man?” fabulous.
At the Slumber Party I had a couple months ago, they had some fun-looking finger vibes, too.
