I'm 28, 6ft. 2inches, 248 pounds, and high blood pressure runs in my family on both sides.  A few months ago when my girlfriend and I started having sex, everything was fine.  Now these last 5 months, I can no gain a full erection, nor keep what little erection I do get.  I'm feeling horrible about my performance, and I know she is not satisfied like the past... What is going on?  Is this normal?  Can it be fixed?
Hello, Please explain what do you mean by full erection? Are you able to perform normal sex and ejaculation? Do you masturbate? Do you use alcohol or cigarettes? What is your blood pressure reading? Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr K. V. Anand, Psychologist
