question for girth and lenght, please help...

Hi there,

I was doing some reading on the A and V stretch, I was just curious on wondering on a few things:

1) Does the A or V stretch work at all or what?

2) How come when using the PJ device for jelqing, why do they say it
affects more girth than lenght and is it possible to achieve only girth?

3) As dumb as this may sound is it possible to do PE and have your penis
get smaller?

4) When I use the PJ device, sometimes it feels as though I’m doing
nothing, if I get too erect my foreskin comes foreward over the head
and it feels as though I’m just pulling the outer skin forward….but if I”m
soft then it feels as though there nothing being forced or done to
enlarge the tissue inside?
