If your like normal people knowing how to get a hard on may be simple but some people need more stimulation to trigger this effect on a male. Sometimes we need to look at some nice porn magazines or videos to get that hard on. If your looking for a great place to pick up some great porn magazines then I have the best place where you can go and buy the best porn magazines on the planet.
They will be shipped to your house so you don't have to worry about what people think of you when your at the counter buying your porn magazine. But back to the problem of how to get a hard on. If you are really having a hard time getting one you can try porn magazines to help the blood to flow to your penis and you can use a good masturbation jelly to highten the pleasure.
You can record yourself with video making you feel like some one is watching, this may help and if you don't care then you can send the recording to xtube or something like that. I would be careful about taking pills unless your doctor tells you that they will be safe for you to use. These pills can cause other problems that you don't want.
If you still are having a real bad time on how to get a hard on then you need to go see your doctor. Only your doctor will be able to tell you what is wrong, it could be just has simple as your diet. Foods and eating right and working out help very much when it comes to how to get a hard on. http://www.magazinehome.org
Also if you don't like doctors then you can try herbs. There are some good herb shops around that deal with natural healing. You can see if you can find a good Chinese medicine herd doctor. They will work with you by teas and ancient Chinese medicine. The Chinese are very healthy and you don't see to many obese people over there. Being over weight can cause many problems for men and yes even being able to have sex.
