Perhaps... a fantasy form would suit you? You wouldn't call yourself much of a gamer but you really did like classic games like Skyrim and World of Warcraft. Perhaps you could draw inspiration from them? Angels and Fairies were boring to you, perhaps you could go the demonic route? After all, demons could pretty much do what ever they want. But maybe not just a full demon. Why not add some other elements too. Like dragons and maybe wolves too. Excited at the possibilities you make another wish.
"I wish I would painlessly transform into a muscular werewolf-demon-dragon tribrid who can breath lightning, is completely immune to heat, fire, and magma, is bulletproof, can fly nearly at the speed of sound, has claws that can shred diamond, and also I wish that the entire transformation is completely pleasurable and that I will orgasm several times before the transformation is complete. I also wish that this wish-granting ring can only be used by me and if anyone else tried to use this ring they would instantly die. My last wish for now is that this ring is indestructible and that I will always know where this ring is at no matter where it is"
After saying that last wish, you can already feel the transformation starting.
