Things I Like Being Hit With

Hands - as spanking, obviously, not someone taking a swing at me. A
good slap on the arse or the thighs isn't going to do you any harm,
and there's something beautifully degrading about it.

Riding crop - gently gently, but I do enjoy the sensation, the noise,
and the look of my partner of choice holding one of these.

Tailed whip/flogger - my tolerance for these is surprisingly high, and
I find used softly or striking with further up the body rather than
the tails, the 'thud' rather than the sting is quite pleasing. Can
also be safely used on the back/shoulders - a good place for me.

Improvised items - If you're being particularly cheeky and your master
has to grab the nearest book/hairbrush/ruler/whatever to give you a
smack with, you had that coming.

and

Paddle - I actually genuinely don't like this feeling, which is why
it's great. There's no 'mmm' to the 'ouch': it just hurts. So if I've
really been bad and you want me to scream, cry, beg you to stop,
there's your weapon.

This is all very "oh please, don't throw me into the briar patch," isn't it? Is that why I liked Bra'er Rabbit so much?!
