PROS:
Shrinkage
Enjoying a smaller cock(according to the file)
Prejac (something I want)
Enjoying being part of the smallish(heh~) club of people who have successfully shrunk their dicks
Easier to cum
Smaller cock means more pleasure per inch
CONS:
If you need to use your cock later you'll have a smaller cock and might regret it
Eventualy you might not have anthing to use if you ever want to use your cock
Someone might judge you for your smaller cock in the future.[/quote]
I can only speak as an impotent, tiny-dicked person here, so I can't really say too much about cumming or prejac as I'm incapable of either (I can see the attraction of prejac, though). Maybe others can add their thoughts there.
The issue as far as I can see from the list of cons is that most of them involve unknowns - eg you might change your mind (not impossible) or being judged for it (though who wants judgmental people in their life anyway?) And being unknowns - I don't know!

Just a matter of using your own judgment, or balance of probabilities or something?
Maybe another way is to just give the file (or part of it) one quick listen through maybe without focussing on it too much, and seeing if you just like the general sound of it? See if it feels right or not. I'm sure you'd know pretty quickly.
