I have done more research, and I discovered an article where a veterinarian on horses talks about the benefits and consequences of riding your horse bareback. Some benefits include, gaining better balance, bonding with your horse, creating less pressure points on your horses back from the saddle rubbing, and gaining better muscles in your legs. Some cons to riding your horse bareback include, some horses have high withers (a horses withers are where their necks meet with their shoulders on their backs, it's where the front of the saddle lays) and if you ride a horse bareback that has high withers, it is more painful for the rider and less effective if you are trying to prevent yourself from being hurt, and, I read it can also be dangerous for your anatomy. Also if you have thicker thighs or if you have a wider horse, your legs will get pushed out more and your lower legs will be hanging. You then can't use your legs to cue the horse properly and since our hips joints can't widen beyond a certain point, your pelvis gets rocked back and forth, pulling you from your balance.
