Mine has the same mild leftward rotation. I don’t have a curve but when I’m erect it is slightly rotated. I also notice it in the pump tube.
Mine is pretty subtle and I’m pretty sure I’m the only one who notices it. My wife has never mentioned it and neither have any of my previous partners. Of course I spend a lot more time staring at my dick than anyone else ever has or will.
I’m not sure if it is because I’ve always "dressed to the left" or if I put my guy to the left in pants because it falls more naturally in that direction. Or if that is just coincidence.
In any case, I’ve not been bothered enough by it to try to do anything about it.
It might be about ligament length or tightness, because I do notice when I am fully erect in clothes it is easier to put it against my left thigh, while if I put it to the right it sticks out more.
But years of hanging, pumping, ADS and clamping have neither improved it nor made it worse. So I don’t have anything helpful to say other than I’ve not had any complaints and I don’t mind it.
