What is the difference between bondage and fetish?

[Haida_lee]

I'm confused by terms in the world of sex. For example, bondage, BDSM, fetish, hardcore. For me, as long as it doesn't hurt the body, it's okay. All those terms don't matter to me, because the ultimate goal is orgasm. Just like I've always done. Here are some of my photos; please indicate what type of sex they are...

Bondage: the use of restraints (e.g. handcuffs/rope).

BDSM: includes the above, as a portmanteau acronyms for Bondage Dominant Submissive/Slave/Sadism Masochism including some if not all these other dynamic aspects at play.

Fetish: a sexual desire or gratification through an object, act, or body part. To the lesser extent: a kink, to the extreme: an obsession/pathology.

Hardcore: ? A qualifier for the porn industry.
