Premature Ejaculation and Orgasm

This is a two part question needing an answer. Firstly, how do I stop premature ejaculation permanently. The only way I can do that is masturbate an hour or so before the actual sex. I don't really want to do because I may not have the right environment every time. I want something that is easier than this.

Secondly, my partner doesn't have fun because she couldn't orgasm. I'm always the one who gets done and that too fast. I always know that I will be releasing fast. I feel bad because I can't even get her closer to her having any fun. I want her to have me too. I don't like being always the one initiating. I'm good at foreplay and we both enjoy that and I'm already hard before I even start that, so I think that's another problem.
