No. Vibrators don't do shit except numb your nerves.

That's what I use. Only thing to be careful of are cheap Chinesium knockoffs - they may not be machined and polished as well, leading to puts and burrs. Some of the worst models aren't single milled pieces but rather coated metals as they're cheaper, leading to the metal chipping and flaking off. I invested in a known brand as I know I'm getting safe products.
