Hi AMT09! This is a great question and I highly recommend this strategy – it really helped me on my dilation journey to integrate a vibrator as I was moving into the bigger sizes. It made things feel less clinical and also opened me up more to having things inserted!
I wish I could tell you the brand I ordered several years ago but it isn’t available on Amazon anymore. It’s a “rabbit” style vibrator with both external and internal stimulation parts, which I highly recommend. You can use it just externally or both externally or internally.
Maze (who runs these forums) has a handy video series about choosing the right vibrator, and there’s also a free ebook with specific brands recommended. That would be a good place to start looking! You can see it here:
