This can be scary at first, second, third, etc.... I never did like it when my friends would decide to just take off into a full gallop without me knowing. I usually like to work up to one so I feel more in control. Honestly, I use the horn every now and then too. No shame. I feel a little more stabile. So What?? Only when you are super comfortable with the gallop and your horse you may never need to use it. Like everyone said, just practice but make sure you are comfortable with your speeds before you gallop. Make sure you can stop that gallop if a situation arrises. All in all, it is exillerating and you look to do more. Have fun with it and stay safe.
