i suspect its a blood pressure drop or increase, either one of those extremes can cause ed, plz consult a doctor.
If there is a sudden change, there can be some medical problem. If you get hard one once a day, it many be normal if there is no other health issues. I think you may check up with your family doctor.
i only get one hard erection once a day before tht it was atleast five times
jjust felt dizzy once in the winters like real dizzy and since then my sex drive is all down hill cant get an errection before that it was real healthy
Consult a doctor if you are feeling dizzy every time. This may be due to postural hypo-tension.If any medica problem is ruled out you may try anal breathing. Google and read it. If you find it interesting you may try it.
