OK, this is a subject I have very definate opinions on... always have!!! My ex long term guy bent downwards alot like you do though you may be a little bigger, and personally I loved it for several reasons. Best being Its alot easier to swallow from below... I cant stand upward curves as they are impossible to suck well... way to much effort. I think your cock is perfect by my standards... and Im sure I am not the only one to agree...
Also when it comes to intercourse, upwards again are painfull.... even much smaller ones. I have always preferred a downward bend, of good size... Your dick is fucking beautifull man...
