Losing erection while standing up

[NSF001]

I can maintain an erection for fairly long while sitting down with an EQ of about 9-10 if i constantly stimulate myself physically. However, when I stand up, it becomes fairly soft, more like a plumply thing.

Should I be overly concerned?

Well since it happens to a few others as well, you shouldn't be very concerned.
What about having sex in a standing position? It can't possibly get soft then, can it?

Its normal, because when you stand up, your blood pressure changes. Occasionally you get a 'rager' that just won't quit like when you pop a Viagra
