Well you see, the blood does in fact rush to our face to give ourselves
face boners, but evolution has introduced the nostrils to humans which
give an opening to the blood, ergo, it is scientifically impossible to
get a face erection thanks to nosebleeds. Hence why japanese cartoons
show boys suffering from nosebleeds all the time. You should always 
trust what anime tells you! ヽ(´ー｀)ノ
