This is my first ever 2D fighting game, so I'm new to all this. I seem to be pretty good, because out of about 100 matches, I won 11. Fear me. But there is one problem - Combos seem 10x harder when I'm facing to the right. My thumb just doesn't go that way naturally. I simply can't do an ultra at all, but facing left, I'm good. I hate when it's a close fight and I want to pull my ultra to win, but I can't because I get K.O'd because I'm desperately trying to get to the right side.

Practice makes perfect.

Hmm, I suck at pulling Ultras off when facing left. I believe we are opposites.

Same here actually, it seems easier to pull of ultras and other moves when i'm facing left. Maybe I just got used to being a second player when playing ranked matches lol!  I don't know, maybe it's just a thumb preference hehe!

you may be missing part of the motion go into training mode and turn inputs on and watch what your motions are when you try to do an ultra. Also what I do is when im facing left I use the tip of my thumb to make motions. When im facing right I use the middle of my thumb where the joint is the make motions.

You're game is prolly broken, you should take it back.

I still mess up occasionally, especially when FADCing(from the right), I use the 360 controller though

I've got the opposite problem. Doing moves to the outside of my stick (so the left) is easy, while doing moves towards my buttons (to the right) is so much harder.

Yell at your hands more often, that seems to work for me.

first 2d fighting? in the 90s 2d fighting was huge. nowadays all about fps. i used to every side cuz i play many 2d fighting. jus play many time in right side u get used to.

i have the same problem...but here's what i think...
when i'm in training, I watch my hands instead of the screen sometimes to actually see what i'm inputing. 
 I notice how much when facing right my point and middle finger dictate your movement without a vast amount of support from my thumb,but when inputting while facing left my thumb stabilizes my movement ,as well as my fingers start to hook  giving better grip because i'm pulling outward..
 facing right i'm pushing foward inward making it much more difficult to control...
 atleast thats my issue on the fightstick...

Everyone's got a bias for 1 side or the other. You've just got to practice to make your weaker side better. That's all there is to it.

Just practice more.
I alot of trouble for awhile with facing left, since I always played as Player 1, but yeah, I got used to it later.
