Hi! ram:
There are lots of reasons why ED, Erectile Dysfunction occurs in men. They range from sexual performance anxiety, the use of medication for medical problems, general fatique due to over-work and lack of rest, and on and on within our physical-sexual-make-up. I would see a good Urologist and see what's going with your ED, problem. Never heard of cucumbers causing ED, but then as you largest sex organ above your shoulders is your brain. Well, Sexually, cucumbers on the brain just may be messing up your sex life. Anything is possible when it comes to our sexual-brain-turn-off.
