Welcome to the Gym! There are a few Asians on the forum. Perhaps they will speak up.
About the penis size issue: It's almost always a psychological issue. I've seen guys who were 9 inches and still weren't satisfied. Crazy? Yes. Uncommon? No. The thing is, you choose how important size is to you. Now, with PE, you also have the power to change your size.
About what to expect: Pick a goal, start out light, and take it a few weeks at a time. Depending on how much you want to gain, you should expect to spend at least a year PEing. It doesn't take this long for everyone, but it's best to think long term.
Good luck, and we're here for support
