I got in by accident.

I don't know, my girlfriend wasn't believing that excuse for a second.

And then when you get into your 30s it's back to the "is this ironic or genuine?" conundrum.

Handcuffs are actually pretty bad for most bondage. They cut into your wrists and can be unsafe in a bunch of ways in addition to being a not-fun kind of uncomfortable. I'd say the best option is to come over to /r/BDSMcommunity and ask around for even more advice.

Sex shops that don't focus on BDSM tend not to be the best places to consult or buy BDSM-oriented toys from. Most kink gear tends to be made and sold in more of a cottage-industry format by smaller vendors and people doing it as a hobby. Most of the mass market stuff tends to be aimed more at the "spicing things up" sort of crowd. So high cost, low quality.
