at 27 years old what can i do about ED?

Lose weight

Stop Drinking caffeine

Stop masturbating

Get. a girlfriend you are. ACTUALLY attracted to.

You could have a serious vascular problem. A competent urologist should refer you to one if he doesn't see any thing else wrong. 

See another doctor who specializes in ED treatment.  You may have a vascular problem that is not mental.  An understanding partner is a plus who can help you.

Thats bullshit psychiatrists cant help with that .all you need to do is be patient reduce stress do t drink or take any drug that depresses the nervous system.

Have you gone to a urologist yet? Look for a Dr that treats sexual dysfunction. Be glad that you do have a option with viagra.

That is not that fast to solve. 

Reasons to become infertile:

- milk and dairy products 

- wlan radiation

- heavy metal poisoning 

Avoid these and do the Klinghardt detox protocol 

After this, start the GAPS diet (Dr. Natasha Campbell McBride)

p.s. ED actually means Eating Disorder

many problems have a mental cause thus the dr. suggest u see a psychiatrist, Its not like the dr. can prescribe a magic pill or tell you some other physical cause. Psychiatrists are highly trained as not just a psychiatrist but as a dr. as well.

You need to find another doctor.  Most cities in the US have Erectile Dysfunction Clinics, you see where the closest one to you is and go there.

Your girl even more. Just take the viagra to make the world a better place.

Have you seen a urologist????
