My husband and I are having a great time with regular threesomes with our girl friend. I've been thinking about going beyond the occasional small vibe and was wondering what suggestions the Eden Community had for us.

He is not all that into toys but is game if we are. I've used a double dildo a little (this one: link ), what else should I look into? I've been mulling over a strap on, is it worth it in this situation? (links to toys would help, thanks!)
