Pressing down on an erection for length gains

The first part makes sense to me, thanks. You lost me at occupying the vacuum.

The amazing isometrics excercise is intended for expanding the gain potential of the ligs. Also, I think it was bird2 who said he used the excercise, helped him with his gains and with the cementing of gains.
Also, it is a pretty known excercise, among porn actors too, raising the we towel with your dick.

But one should really be very careful with this one.

There are inner parts to the penis which are fixed to the pelvic bones by ligaments and muscles. They are attached at an angle that (in most men) causes an upward pointing erection. The ligaments add support during intercourse and help keep the erection centered, but they are not the main reason for the upward angle.

NOOOOOO!!!!!!

NO! NO! NO!
