I find a longer paddle delivers more of a stinging thwack sensation, whereas a round paddle provides more of a thud. You might want a paddle sex toy that is small enough to paddle an inner thigh or one cheek, or a paddle that's large enough to paddle both cheeks at once.

Material Matters
I’ll start you off with a soft sensation, like a paddle that is fuzzy, furry or padded on at least one side. These paddles can be sensual. You can rub a bottom sweetly with them. Soft paddles are a perfect tool to warm a bottom up or bring it back down to earth after rougher play. These kinds of paddles can also be rubbed on any part of the body for a soft tease.
Next, leather. Leather can amp up the sensation. How soft or hard the wallop will be with a leather paddle depends upon how soft and pliable the paddle is. Sometimes, you will find a leather paddle is actually wood wrapped in leather, which would provide a harder wallop. Other paddles are almost floppy, like a belt. Floppy can be softer or stingier, depending upon the length and thickness of the leather.
A silicone paddle delivers a very unique sensation. It will be light in your hand. It will feel smooth and sensual to the touch, but these babies can really deliver a deep sting without a lot of effort. I highly recommend you start with a softer swing and graduate up to something harder if your partner wants more sensation. A silicone paddle is also perfect for someone with limited mobility. You can deliver a deep spanking with a small amount of effort.
