I do not have prostate issues, but some off and on ED issues, but I have discovered my frenulum (underside of my penis head) is a very nice place to stimulate to orgasm and ejaculation. Even when I remain mostly flaccid I can always achieve orgasm and ejaculation by masturbating the frenulum with well lubed fingers. Reading erotic stories or viewing adult pics and/or video clips help increase arousal toward orgasm. Hope this helps. Try not to let the pressure/pain build up. Stay ahead of it my making yourself cum everyday or at least every other day.
