I think it's excellent that you decided to start with a safety. If and when you decide to start straight razor shaving, you will have an excellent fall-back device that you can use to either clean up your shaves with the straight, something to use if you don't have time to use your straight, or just plain variety.
Eventually, as you learn to use your straight, you may come upon a time when you don't need your safety to clean up your shaves with a straight. Even so, I'm sure you'll always find time for your DE.
Congratulations.
