The real answer to the OP's question is that he will enjoy riding when he decides he wants to enjoy riding. Then he will reach out to learn how to alleviate the things that cause discomfort and the like, instead of asking people he doesn't know when he will start to like it. That's a question nobody but the OP can answer.
It's like me asking when I will start enjoying broccoli. After 60+ years of never liking broccoli, nobody can tell me when I will start liking it.
