This toy is purposely designed as an anal plug, and is definitely great at that, but it can be used vaginally too. The bulb base makes for a good gripping point and the thin neck really helps it to stay in place, especially if you like something not as thick, but longer. Being that this toy stays put very well, you can have it inside, or out and about. I would be careful on using too much lube though. combined with the glass it can be slippery and you dont want it falling out. Addi tonally it is a bit pointy and long so be careful doing deep or sitting down.
