Seconding Titleist, it takes time and dedication. Most people here that have stuck with a routine and used all of the positive indicators that are talked about here can gain pretty much limitlessly… but it takes YEARS.
You’ll probably get newbie gains as you stretch out parts of the unit that have never been stretched like that. Most people see about a half inch in like 6 months. For long-term gainers (like Titleist, and somewhat myself) we can reach kind of whatever goal honestly. I started at 7, now at 8.5, looking to reach 9-9.5 or whatever depth makes my wife demand I stop. Quite frankly, I’m 40 years old, and have my 5th kid on the way. I almost just want to comically see how big it can get LOL. I will tell you that at 8.5 it is starting to get a little unwieldy on a day-to-day basis, but I love that.
I just posted on another thread, but your goals are YOUR goals. It’s not a size contest here. Just a bunch of dudes supporting each other and normalizing something that has a pretty social taboo.
Do your research on the forums. Get the newbie routine under your belt before trying anything else, and I mean for like at least 6 months to a year…. The penis is a VERY sensitive organ and is made up of a whole bunch of things that have to work in concert together. Some of the more advanced stuff will break your unit if it is not ready for it.
Look for the positive indicators, you can search for them through the forums.
It’s not a quick-hit. None of us here support that mindset.
Welcome!
