Welcome! You mention being happily married, but are you happily employed? Because getting your first tattoo on your hands/fingers is generally not recommended.
I would strongly suggest you get a different game related tattoo somewhere more concealable first, then progress to your hand at a later time.
That said, if you're set on getting this tattoo anyway, you need to make it so that the letters are readable to others, NOT yourself. So W and S are on your middle finger, A is on your index finger, and D is on your ring finger. This avoids the issue of any tattoos being under your ring also, as "A,S,D" can all be in a straight line along your fingers (below the first knuckle). Unfortunately this does mean that when your fingers are actually on the keys the A and D will be switched; I feel confident you'll still be able to figure out where the keys are though.
Again, I'd like to reiterate that fingers is a poor choice of placement for a first tattoo. You're an adult though, so do as you'd like. Just don't get the letters facing you because that's upside down.
