I haven't been on this site in over two years because of having Prostate Cancer. I have Advanced Metastatic Prostate Cancer which is incurable, so it's all about some treatments to extend life for who knows how long.
I won't go into details but I can assure you that if you become metastatic, your sex life is OVER. Between the surgery to remove the prostate and the hormone therapy after you find out you still have cancer, there is nothing left of your dick except limpness, incontinence, numbness, and no libido.
So fellas, take it from me, get your PSA Blood work done at least once a year once you're over 40 and twice a year if you're over 50. It's a complete shock to the system and way of life you are living now. You can live for a while, but it isn't pretty.
