You should talk to your doctor if you really want to use Viagra, and get a legitimate prescription, and then talk to your pharmacist when you get the prescription filled.
Viagra can be dangerous. It can affect your vision (usually temporarily). If you are not having erectile dysfunction, you really really should not "play around" with ED drugs. It can seriously fuck up your circulatory system if not used properly.
Viagra works by dilating a few blood vessels, and allowing a little more blood flow to the penis, if that blood supply is impaired. It will not cause erection without stimulation. If you already have normal erections, it may have some very small reduction of time between completely flaccid and fully erect; it may help you stay fully erect if you tend to go limp during sex.
If you don't have dysfunction, the considerable risks are not nearly worth the negligible benefits.
