Hi there ~
I understand your concerns. I believe that you are having weak erections due to medical problems, i.e. uncontrolled hypertension
. If that or obesity that you mention is the case then dealing with these issues with medications as well as changing your lifestyle will improve your erections. Also consulting a doctor qualified in sexual health issues to see if you fit the profile to get prescribed medications for erectile dysfunction
might be helpful. I hope this helps allay you anxiety
Take care and have a lovely day!
