Another method of hardening your penis, and thus
masturbation, is Jelqing, a technique intended to enlarge
the penis by increasing the blood pressure to
permanently increasing the maximum size of the
penis. This is also called "milking" and is done by
wrapping the thumb and index finger around the
penis in a semi-erect state and repeatedly drawing
them away to force blood into the glans. However,
jelqing, though popular, is still a subject of controversy.
However, it is said to have various Arabic origins while
other sources claim the technique has roots in tribal Africa
particularly Sudan. Still, others maintain that this was ancient
Russian tradition, especially practiced by midwives and mothers for
their sons early in life t be naturally endowed later on. But whether it can
enhance the size of the genitals or not it’s a great way of stimulating yourself.

Finally, there is Clamping which is a technique that uses a constricting device, like a shoe string, cable clamp, a tight cock ring or anything else that will serve to this purpose. The clamp is then firmly tied, clamped, or put, on the base of the erect penis while "edgeing" or while extending masturbation to have a firmly erect penis. This method is widely considered as an advanced penis enlargement routine though it is very dangerous, even more than jelqing, since it significantly cuts off blood flow. But if it suits your taste, must be very careful and let it not be performed by those who are new to penis enlargement and such.
