I don't mean to burst your bubble here, but your dreaming if you think your going to have an inch in 2-3 month with a girth of 6.5!
not to mention, you could just be a hard gainer.
people have gained length quickly with larger girths, but that's with an
extender and manuals not pump, plus if you've already gained from pe then your newb gains are probably exhausted, have you ever done pe before?
Anyways, i've read your other posts and you seem to question wether its going to work alot, which leads me to wonder how much effort your really putting in, if you don't really believe in something then your not going to put your heart into it, and in pe you have to.
The reason im posting this is because it pisses me off when people decide to give pe a half ass try, or maybe even a genuine go, then after a month or 2 they post threads about how they havent gained and it not working, which is annoying because it discourages other guy who come across the forum from even giving it a shot!
If your not gaining then switch your routine up, not to mention there are so many factors that can be a cause for why you feel you arent gaining, anything from not measuring in the same place, to a weaker erection, to really not gaining, to not putting in enough intensity, to not having a good enough routine, to not using baby powder as a proper grip when you stretch!!
Do you use baby powder when you do your manual stretching?
