How get an erection?

You should get that automatically and upon arousal. If you really like a girl (or guy if you are gay) enough to want to have sex with them and you see them, chances are, you will get an erection.

There is really nothing to do, unless you want an erection for masturbation. In that case, get a magazine or an image in your head, and then start masturbating, even if it is still flaccid. The mental and physical stimulation should cause an erection.

If you have difficulty getting erections, you can see a doctor and get medication for that if your health allows you to use such medication.
