Confidence...
Possessiveness... Verbal and physical...
Being bitten....especially on the neck, shoulder, back, thighs, butt, breast...
Hand necklaces...
Pet names (as mentioned above) Baby Girl, Kitten, Baby Doll... But also a affectionately degrading ones like... Little Slut, Fuck Doll, Fuck Toy... Extra points for putting the modifier "My" in front of it...
Growling... A good, deep, rumbly one.. Mmmph!!
Willingness to submit, experiment, and return teasing either through vocal or physical means.
Scratching / Clawing, mewling, biting.... fight back, make the hunt fun.
Daddy, Sir, Master - Ungh - That being said, I'm all for affectionate names, like being called a teddy bear and things along those lines. Though, the first one of those three is reserved for one person especially.
Also, one big turn on is if I take my belt off and their eyes light up along with their cheeks.
