Funny thing about penis direction….. during jelq…
I generally will stand with my back slightly arched, hips forward, With an 80 - 90% erection. I will start with a PC flex, grab tightly on to the base and jelq toward the head as I point the penis downward about 45 degress. As I near the end of the stroke, I will lift upwards on my shaft to where it points straight out or slightly upwards, pc flex, then grab the base tightly again and jelq with the other hand again, shaft pointing downward.
For me, I feel like: the pc flex, hips forward, tight grip and downstroke really trap blood in the penis. Then when i lift up and release where penis points straight out, I get max bloodflow.. Then i will trap all that blood again on next downstroke. Throw in some pumps and other s queeze variations and when I am done, my cock is heavy and pumped. It looks like I just used a vacuum pump, but noticed it stays pumped longer and is heavier. I am very careful though when doing these.
