To those who are seemingly offended and confused about why anyone would be interested in or talking about the curve of their penis, don't bother reading through this forum then. In short, an answer though is that naturally we (people) are curious about things we do not have a lot of experience with. Obviously in society, being nude is a bit of taboo and even bigger taboo is observing or giving attention to the penis - flaccid and even more so erect. Thus is makes sense to be curious about and compare 'notes' on the subject. That is all and I don't think it should be seen or confused as anything more crude or sinister.
That all said, my penis has a bit of upward curve and also a bit to the right. The upward angle has reduced as I am getting older and the right bend has developed as I get older. In my younger years, mine pointed almost straight up and was straight left to right.
