At 24 get healthy, pack up smoking, cut out any alcohol, cut out any fast food of any kind, get exercising, walking, do some jogging, get yourself in a gym, start to think healthy and you will be healthy and this should help your sex life.

my age is 24, and now days my erections during masturbations are good but not that strong, it erects naturally when i see some hot girls or like that, but since 2 months when i try to masturbate while watching porn i have to make it erect by masturbation coz erections are not strong enough to masturbate....
What's your age? How is your erection during masturbation?
If you masturbate using only sensation (no porn, etc) what is the quality of your erection?
A healthy lifestyle is the #1 ED treatment, so I suggest you quit smoking. There are countless studies that show that there's a connection between smoking and ED. Get some exercise and try to improve your diet, too. If your problems persist, then you can start thinking about seeing a urologist.
