Heck, don't think I've ever gone cross-eyed either [:-]

Like adams, I shoot right handed, yet I'm left eye dominant, which should be the hardest way to shoot with both eyes open; yet it has been pretty easy to learn.

Like someone else said, I believe I started by looking through the peep with one eye open and then after acquiring the target open both eyes. It wasn't long at all until I started having both eyes open from the start and never even thinking about it...

Now if I try to use only one eye it feels very awkward and like I'm handicapped.[:'(]
