SimonClass:
I don’t think I can give a significant contribution about your questions, because I didn’t observe any changes about curves or erection angle. My unit was straight and continue exactly like that after some years or PE.
I’m dexterous, but had always the care of do the jelks (and other exercises) with alternation between the right and the left hands. Your question conducts to one other question: Why 85% of the lateral curves are left and the right curves are rare? I don’t know what are the percentage of dexterous and left-handers in male population, but I think there isn’t a simple coincidence if these percentages are the same or close to the distribution of percentages of curves observed. I think the men who use predominantly the right hand to masturbate tend towards left curves in their penises, and the left-handers the opposite. Isn’t a interesting theory? Si no e vero, e bene trovato…
