[/INST] Hello welcome to Healthcare Magic.It looks for me like problem lies with thinking. As you are saying erection is good in normally so some systemic disorders will be ruled out.I would recommend counselling if you are my patient.I am assuring you not to worry, things will get well soon - take care.Need to ask ? Do not hesitate. Thank you. </s>
