Dear Customer
Welcome, and thank you for trusting us
Regarding what you mentioned, the erectile power of the penis will decrease by age so it is normal at 54 years old to have a weak erection in comparison with the erection that you have during the previous years .
If you are able to have a normal sexual intercourse so this means that the sexual ability is ok.
You can use a taldanfil to strengthen the erection but we have to be sure that you do not use medication which may interfere with this drug such as nitrates that is used in patient with coronary artery disease.
Therefore, we advise you to visit the internist doctor so that the doctor could do a full clinical evaluation of the case in order to confirm that everything is ok.
  Stay well.   
Feel free to message me anytime here if you have further questions.
It is our pleasure to help. Please feel free to reach out to me anytime.
