Because they are designed to fit over the clitoris

The main difference between a rose vibrator and a real flower is that it's designed to look just like the flower, but it has several key differences. Because they are designed to fit over the clitoris, they can be used on other sensitive areas of your body as well. They may feature varying levels of intensity and may have different features such as adjustable speeds, pulsing actions or heated vibrations such as phone controlled vibrator.It's worth trying out a few different types of stimulation to see what works for you: if one type doesn't get you off, then there are plenty of others that might!
