Regarding the problem of erectile dysfunction
, it is caused by reduction of blood flow to the penis.
It's mostly related to anxiety
that whether you will be able to perform or not.
So...don't worry about all this & stay relaxed during intercourse.
Performance can be improved by taking a diet rich in fruits, vegetables, fish, nuts & honey.
You can also do oil massage
of the penis...it increases blood flow & maintains the erection.
One more thing...avoid consuming any over the counter medication
which claim to improve performance...it may be harmful.
Best thing is to eat a healthy diet, exercise regularly, avoid stress, get good sleep, think positive and stay happy.
Wishing you a Healthy Life.
