Hey Tony!
On top of the excellent comments from Alvee33 I would add that an electric with some Overdrive/Distortion and a bit of 'Verb or Chorus or Delay or all 3 or more/different can hide a lot of sins.
Don't get me wrong, I'm not being Acousticist/Electricist here, I'm talking about when you first pick up the guitar for a playing session. As the sound you produce (on top of what/how you play) is largely governed by electronic sonic enhancement of one sort or another (longwinded way of saying Preamp/FX) you only have to play an open string for the sound to be just right and it 'warms you into' playing.
With an unplugged Acoustic, all sound is down to how you play the guitar.
Beyond this everything is pretty much what Alvee said: Acoustic action usually higher meaning harder to fret notes and much harder to do string bends, etc.
If you want play both, do just that. An hours practice devided equally between Electric and Acoustic (maybe after spending a little more time with Acoustic to catch up).
It certainly isn't you! I consider myself an extremely proficient guitarist (can play in front of almost any audience, make them like me and make them think I'm good (some people are easy to fool)) but give me an electric and I sound crap!
Playing both is like being ambidextrous - which I'd give my right arm to be!
