It is possible to increase the size but this is usually
for men with smaller size not for guys with average or
larger.
They cut a tendon at the top to make the penis drop lower
so it looks longer when soft but it is not much longer
than before the cut, I believe maybe half an inch.
They can also cut the bottom line of your penis and
put in a fat graft under the skin to make it look fatter
but I believe the body consumes the fat over time.
I have seen it done and it did look bigger than the
before pic's.
