What do you see as the basic essentials of D/s- can you have a working relationship with a sub without play or sex?

Just curious what people think?

For months I've had one with a y/l I essentially 'own'- we've never really had much play, partly because of her age & also because she's lacked privacy til now.

Of course I'm one of those who believe you can have love without sex....
