I have a downward bend too :( (and a little to left). I recently started to jelq the left CC more than the right, and use a bending action to the right and upwards. I can’t say Iv’e altered the curve one bit; maybe over time. Iv’e just got a bigger dick, which ain’t a bad second prize :D . That being said, I have, in the past, mainly worked on flaccid stretches for length, so more jelqing and girth exercises are the way forward (upward).
Erection angle changing? Pass. Mine would be good if I could straighten the bend. (base starts at about 10.30 if that makes sense)
Like MDC I haven’t seen pics of proven results. Check this thread for some hope- it seems to pop up when curves are mentioned.
