I am a flight instructor CFII, commercial pilot, advanced ground instructor and instrument ground instructor. I do not have rotor.
Flying fixed wing is something that requires lots of time and practice only because everyone grows up riding in cars and therefore it comes naturally. Since most have never been in a cockpit everything has to be learned over and over. You practice with a flight instructor till you get it right and then you practice till you can't get it wrong.
You can learn in a typical nose gear vs taildragger requires about the same time from someone with zero time. It's not harder, just different.
As a side note I had a student that threw up every time we went up. Flights usually last around an hour and later on a little more. He it took a while to get that amount of time before he would throw up. He was persistent and ended up getting certified and is flying to this day. I learned, from him, doughnuts and coffee are the worst to hurl up in a cockpit. Orange juice the best. It smells the same going down as it does coming up...be kind to your Flight Instructor.
