P.S. I can't edit posts, so I'd like to add a few notes.
i. Flex your pubococcygeus muscle while pumping for stronger, harder erections and better ejaculatory control. A strong PC muscle helps your overall sexual health and performance. It's also a fun trick to make your penis swell, which your partner will enjoy.
ii. Don't complicate things when pumping. Trying to use a cock ring, prostate stimulation, etc. might seem like a good idea, but its better to focus on just pumping while your hands are occupied.
iii. Just for fun, I recently ordered some Doc Johnson Plump enhancing cream. You have to rub it gently (start with a small amount) into your erection for more than five minutes – the people who complain about it probably didn't do this properly. It really does seem to work. Vacuum pumping gives you far greater benefits (and even looks) and is free, but you have to appreciate how the cream works. There are some stimulant/irritant chemicals in its ingredients, while the rest are moisturizing/stabilizer compounds. Your penis will look slightly redder with the veins popping out, and I found that my erection was bigger and harder as well. It may be a placebo effect and all that rubbing and stroking has to count somehow, but I am happy enough to order it again. Don't expect an unrealistic improvement, however.
