Tips/success stories for overcoming ejaculating while semi-flaccid?

Title. I think for years when I have masturbated, wanting to get off, I got used to not having a strong erection while doing it. So now as I try to improve it feels like a catch 22: I can’t get hard so I masturbate to stimulate an erection but cum flaccid. If I don’t masturbate I don’t get to train myself? Just looking for any guidance thanks
