I just bought TWO vibraters and both of them just don't seem powerful enough😢 I'm used to using my electric toothbrush which really works but I got these two from groupon and it takes me wayyyy longer to get off with these than my toothbrush. send me pics of your fav vibraters or links!! does anyone else just feel like the vibrations aren't "wide" or go back and forth wide enough and just give you a tingly feeling ?
