The Curvature of my erect penis has normally been slightly downwards. About 6 weeks ago I noticed this curvature has changed and the half towards the tip is now tending upwards, while the lower half is either straight or nearly so.What could the probable cause be and could it give rise to complications in due course. There has been no pain or other unusual sensation/occurance.
An obvious change in curvature of the penis!
I don't know your age; but I suspect it's normal physiological change.A nice curve upwards is normal; and usually enhances sexual pleasure for your partner a bit.
If it's a slight change and it doesn't continue, I'd go with Hawker and say it's nothing to worry about. But if it continues changing, then it may be the early stage of Peyronie's disease.
