Restraints -- whether they're silk scarves or leather cuffs -- are all about letting go and being deeper in the moment.
I wouldn't necessarily consider using sex toys as being kinky, probably depends on the toy. A double headed dildo for dual anal play... that's kinky! But using a dildo in itself, isn't (now on a strap-on... yes, that's kinky). It's too common play for women who need to get off at various time during the day and can't get at their man.
With my fiancee the sex is fairly vanilla, 69 occasionally and doggie when we know we have time for a second, 'cause i reach orgasm really quickly in that position, so I want to be able to go again for her BUT overall it's amazing, it leaves us both in extreme euphoric states -- easily some of the BEST sex we've both had. I know it has everything to do with our connection with each other, the love and passion that we feel for each other and the desire to please the other and please ourselves.
Delving into the kinky side of things is something we've both talked about from time to time and well probably get more into exploring our fantasies when we more out of the shared apartment that we're living in. Hard to let it all lose when roommates can over hear.

Does Tantric Sex fall into the kinky category?
