When will my male organ grow?!

In case you don't want to read my full sad story: 14. Been spanking my monkey for 3 or 4 years and my Un erect junk is smaller than my . When hard it's 3 or 4 inches. When will it grow? I am 14 years old and have been getting erecting since I was 10 or 11. I discovered sex a while before that, while surfing the web and was hooked. Ever since my erections came, I found a tutorial online, headed to the bathroom, lubed up, and started spanking my monkey. It hasn't seemed to have grown much in its in erect state, though. I guess Erect it's about 3-4 inches. Un erect is about 1-1.5. Maybe 2. I read that testosterone is needed to grow a larger penis and that if you masturbate too much it takes time for you to heal and that energy goes into healing rather than growth. I've abstained for the past day but it gets frustrating. I just feel like I need to always spank that monkey, but I also feel as though not stopping will lead to minimonkey forever. I even started drawing porn once I got off the internet for a little. What I'm waiting for in puberty is a big penis! No pills or supplements that say natural in ads.
