Hi there ~
You have a very common problem of erectile dysfunction
and it can be easily treated with medications available during this time. The class of medication is called selective serotonin reuptake inhibitors and it also helps with decreased libido which is a result of depression
if you are going through one. I advise you to consult with a qualified psychiatrist
who might be able to help in this regard. I hope this helps.
Take care and have a lovely day!
