Hey Motician!
Welcome to Thunders.
Great advice already given. Just want to add That should jelq with an erection level between 40 and 70%. Do not grip too tight, just enough to feel blood moving up the shaft. When stretching, grab your shaft about one inch below the glans and do not pull too hard, just enough to to feel a slight stretch. Let your PIs be your guide as to how hard to peruse your routine.
Once you have completed the beginners routine you might want to consider investing in an extender, some guys have reported good results in reducing their curves with an extender.
PE safely and good luck with your endeavors.
