Cuffs are awesome. If nothing else, they're good for freeing up your partner's hands to do other stuff . They are my favorite (I'm so plain...)

I think blindfolds and gags would also be interesting. And I would LOVE to have a collar and leash (my guy mentions it every now and then, no moves made to actually get them, though )

As for floggers, paddles, etc. I have not tried them. Spanking is nice but my guy prefers just using his hand. I am not against them, though. Come to think of it I'm not really against any BDSM stuff... except CBT stuff (just not my thing, I'm strictly the sub).

anything from sportsheets. I think they are a good quality, and the cost is not too high. They dont leave marks on your skin, and are comfy to wear for long periods of time.

Restraints, Paddles, blindfolds, whips nothing to extreme....yet
