Hi and welcome to HCM. Thank you for your query.
It is definitely part of ageing an dmen in your age suffer from mild to severe impotence
. It can be managed by certain medicines and you should consult yout urologist
about it. ALso there can be prstate hyperplasia
which can cause blood flow to be reduced so you should do prostate ultrasound
to rule this out. WIsh you good health.
