I may have control issues, but I'm okay with it.

“Slavery is unconditional.”  A quote I saw of someone defining slavery in the BDSM way of things.

No. 

I mean, perhaps the strictest definition has it so, but in the BDSM lifestyle, slavery has its conditions.  If there is no love, then the only thing inspiring obedience is lust or fear.

Lust is fun, but once the lust is sated, the obedience may slide with it, or at least the passion for obedience does.  There may be obedience out of respect for the dominant, but slavery in BDSM requires passion.

Fear is just wrong.  (No I don’t speak of fearplay, which I do not enjoy or like, but I understand the difference between fearplay and real fear)  If someone obeys because they honestly, truly fear for their well-being, they are not a slave, they are a prisoner.  Unfortunately this happens, and there are those that fear being alone so much, that they live as that prisoner.

Slavery, D/s slavery, or submission, however you wish to define it, is very conditional on love. 

When she loves him, she needs to please him. 

When he loves her, he needs to protect her.

I love her.  I need to protect her.  I have passion with her as my slave.
