Once folks find what turns them on, explore it and progress, it really is difficult to go back to being satisfied with just vanilla - however, this does not mean that you can't go back to vanilla period. BDSM doesn't overwhelm and snuff out the vanilla things you like unless, well, you really didn't like the vanilla snuff much anyway and don't care when you see it thrown by the wayside.

There are as many BDSM/vanilla combinations out there as there are couples, frankly. Some are 24/7 Lifestylers who accidentally slip up and slip in a little vanilla action now and again, some are vanilla with just a hint of kink thrown in a couple times a month because it switches the routine up a little.

Totally up to you and your girlfriend to work out what your balance is going to be.
