I have a thick spongiosum. So much so that I can't always perform the "okay" grip, especially when greater than 50% erect. I find myself having to do a modified overhand v-jelq where I basically keep my thumb and pointer finger parallel to one another and pointed toward the floor. I find this is the best way to keep getting an engorged glans during a jelq. However, I believe this causes me to put more grip on the spongiosum and neglect the cavernosa.
I'm just curious if any other guys out there have experienced the same issue and if so do you feel it negatively impacts your jelqing efforts and have you come up with a different jelqing technique to compensate?
