Great alone or partnered
This is an excellent and versatile toy. My fiance and I enjoy using it together and its her favorite vibe to use alone. I suppose if you're Jonah Falcon sized it might cause some problems, but within general bounds there shouldn't be an issue. You will probably want to use lube if using it together as it can cause some uncomfortable rubbing for him, but it's worthwhile as it adds a lot in any position. Part of the fun is thinking of different ways to use it, although I guess you could always just cheat and check their site for suggestions. Although definitely a significant investment, it's been absolutely worth it for us.
