Keep losing any kind of wood while jelqing

I just started jelqing for girth gains, and while I can get myself into the 50-80 percent jelqing range by masturbating, after about 4-5 jelqs I’m probably back down to 20-30 percent. Do people have suggestions on what to do in this case?

Thanks!

Grip with your second hand a before you release the pressure of the first hand. You can actually add it a bit before the first hand reaches the glans. Also release less often and edge, it should make you hornier.
