Hello Tanta, welcome to PEGym!
It would be a good idea to take your starting measurements (flaccid length, flaccid girth, NBPEL, BPEL, and EG) as soon as possible, to ensure you're able to keep track of gains with complete accuracy. It's also useful for other forum members, especially newbies, who tend to be able to empathise better with people who are a similar size to them.
Just in case you don't understand any of the acronyms I've used or that you see around the forum (there's a lot of them!), check out
this thread.
Best of luck in your goals, see you around.
