So i am 7x6.4 my girlfriend and everyone else i have had sex with loves it, and i can work it well but i wouldn't mind being 8x6.5 should i go for it. My only worry is that once i hit that length it wont stay there after i quit the exercises, i want it to cement at that length. I also dont want my man to get hurt he works now fine for hours at a time i want him to continue to work. I also want to gain permanent size fast as possible. SO what should i do guys.
