What is your favorite sex toy? I'm looking for everything: girl toys, boy toys, couple toys, kinky, vanilla, wireless, strap-on, internet-accessible, plug-into-the-wall, looks-like-it-should-be-illegal-in-49-states; you name it, I'd like to hear about it. They've been brought up before, like in the masturbation thread, but I don't think they have their own thread, and I'd like to get opinions from all of you. I collect them obsessively, so if you have something unusual I probably don't have, feel free to mention that too.
I'm also interested in toys for boys that have worked out well for you, because other than prostate stimulation, various vibrating cock/ball rings, and e-stim stuff, I haven't seen a lot out there (other then the fleshlight, which I've never really heard good things about).
If you're going to post multiples, let me know which one is your absolute favorite. Good sites that review sex toys are also welcome, as is anything that's vaguely relevant. Thanks!
