Regarding the problem of Erectile dysfunction
, it is due to decreased blood supply to the penis.
Though medications like Cialis & Viagra increase blood flow to penis & maintains erection...they should always be used as advised by the Doctor.
It can be improved by having a diet rich in fruits, vegetables, fish, nuts & honey.
Regarding the problem of premature ejaculation
, it's mostly related to anxiety that whether you will be able to perform properly or not.
So...don't worry about all this & stay relaxed
Avoid stress...practice meditation
..this helps in improving concentration & builds up the confidence level.
Avoid smoking & alcohol.
One more thing...avoid consuming any over the counter medication
which claim to increase the size of penis or improve performance...it may be harmful.
If symptoms still persist...it will be better to consult a Urologist
to rule out any organic cause.
Wishing you a Healthy Life.
