Hi Scott, welcome to this forum!
Take a look at the “Size’s PE Data Site” - you will find the link at the bottom of each page.
Many have logged their progresses in that database. Maybe you find a similar starting size and see their gains.
But that doesn’t mean, you WILL gain that much, too. Maybe more, maybe less, slower or faster.
I am still to new to PE and this forum to tell you from my success stories, but one thing is sure:
PE works. I only worked on length now, not on girth (I also read, girth is harder to increase) and gained a little bit.
You should also start with length exercises, because the thicker your “friend” gets, the harder it is, to
achieve length. Well, that’s what I’ve read and it sounds logically.
Many wrote that hanging/Stretching increases the girth at the base (near your body) of your penis.
I have the same feeling, but since I didn’t measured that, I can’t say for sure.
Though I read many threads, I haven’t heard that hanging decreased girth.
If you will let your wife now about PE? That’s your thing. There has been a thread lately about that.
Use the search function at the top right of each page to search for things/topics you want to know.
I hope to have helped you a little bit. Greetings and happy gaining,
JohnJohn
