Die hard reversal reader here !
That said there's nothing wrong with reading only upright. Personally I'd to have a talk with my cards about that.
"Ok cards, I'm only reading upright, so don't bother reversing yourselves, got that?"
Yeah I talk to may cards, like they are employees or small school children, it probably doesn't do any good but it makes people laugh
Then I'd put them all right side up, and prolly pick up the deck upside down ! (I have very sarcastic cards
(Actually this happens to me when I read Lenormand, I'm constantly getting the entire deck upside down!)
YMMV

I don't think it changes the meaning, as long s you are clear in your intention, that your aren't reading reversed.
If you do want to start reading reversed, an easy way to start might be with the court cards, if you are familiar with their personalities and looks. You can just append the word "NOT" to the court cards, as in, "You are going to meet someone and he is NOT going to be the King of Swords".
No idea how the cards reverse themselves or un-reverse them selves.
