Has anyone used Doc Johnson's line of bullet Mood vibrators (Mood Powerful, Mood Playful, etc) inside dildos with bullet slots? I'm considering using the one I have in a Leo or Mistress and I looked at the specs - it seems like it would fit.
People put bullets inside dildos all the time. You just have to find the right fit for the dildo and whatever bullet you prefer because the vibrations may travel differently with different bullets. Good Luck!
