Sex after prostate removal

Hi there.. this is my first post so please bare with me..

It’s nearly a year now since I had my prostrate removed because of the dreaded cancer.

i just wanted to ask if there is any men out there who have had this surgery and ask if they have difficulty in having an orgsam..,I really feel the need to release as I’m frustrated but I am finding it very difficult to orgasm .. is there anyone else experiencing this and does anyone know away to overcome this?

thanks
