In my experience, just like women, different men like different things. While a nibble here or a raking there may make one go crazy, it may make the next one run. For instance, FWB loves to have teeth ran across the under side of his shaft, just below the head. It drivings him wild! He also loves bites and nibbles on his inner thighs. SO, on the other hand, wants nothing to do with biting unless he is the one doing it. lol
