The other way to get a lot of temporary expansion is clamping. So if you're looking for something else, then I would try clamping. Other methods would be using a regular air pump, manuals, or injecting silicone into your dick (not recommended).
If you're new to Penis Enlargement, I wouldn't clamp. Or if I did, it would be very short periods of times. It's an advanced exercise.
Regular manuals- with slow squash jelqs, erect jelqs, isolation compression squeezes, toilet squeezes, etc would probably be your best bet. Then mix in some clamping afterwards, with the time you do it based upon how experienced you are in Penis Enlargement.
Make sure you put on a cockring afterwards to help keep your expansion.
