Is it normal that my toes are wrinkly?

Obviously this is not normal. I should know, I'm Captain Obvious! Basically you do indeed have an infection. You need to see a doctor about that. The human body is not supposed to do that at all. You also need to stop not believing in not washing your and feet. It's not healthy either. If your boyfriend is worried about your health, he's worried for a good reason. The kind of behavior you are doing is could be lethal for a diabetic. The infection is could also be lethal if it gets worse. If it does get lethal, you may need your legs amputated. The behavior you are exhibiting and the infection could lead to an early death. No mentally or physically healthy person wants to die an early death at all, this is very bad.
