While this topic and many like it generally are peppered with bickering and arguing I typically tend to be an observer and not a contributor but this time I thought I would try to help the OP and any others mystified by the desire to make it bigger.
First, I come from a medical background but no longer, in that field but still qualified to clear some of the misconceptions of this subject up. While plastic surgery, if done correctly, can give extra size, length, or girth but generally minimally and is usually done as a corrective measure vs. a cosmetic enhancement. Hence, most insurance will not cover it for cosmetic enhancement but if you have several thousands of dollars just burning a hole in your pocket I am sure you can find a surgeon who will slash for the cash.
Second, stretching can and does work! In my previous line of work, we use-to-use very specific and very time-consuming ways to make skin, tendons, and ligaments and yes even bone lengthen. All methods took time and can/could be EXTREMLY painful but it worked, and sometimes with unbelievable results. This same concept is used to make the penis grow. When cells are put under constant gentle tension they WILL divide and multiply
I am not dragging anyone through med school and basic biology but consider how earlobes and lips stretch. Very obese people after losing dramatic amounts of weight the skin often times must be excised because it WILL NOT reabsorb (shrink). Same with the penis!
Third, pumping has worked to actually restore foreskin length, I know not only because of my past but because I have been pumping for years now (on and off) to increase my foreskin. The principle is the same as above to increase but as for permanent gains in length the pressure does work but takes, a tremendous amount of time, dedication, and patience to avoid long-term and possibly permanent damage
do some research on how to pump properly. Once again cells dividing and multiplying!
So does this end the debate? I doubt it! This is just one of those subjects that will create wild and often times misconstrued perceptions and not likely to go away anytime soon.
