Oscillators are like vibrators but they have a back and forth movement. Try oscillator's one time and you will be a believer and you will love it. You won't find a lot of oscillating vibrators out in the market but when you do you will want to consider buying one. These oscillators give you the sensations you desire and then you can turn them off, put them into a drawer and it will be there waiting for you when you are ready. What a concept!
