Is my penis too big, too small, or just right?

I am 12 years old. My penis is 4 inches soft and 6 inches hard. I am also African American if it matters. I have been doing research on this topic and it says that the average penis size is 6 inches but 6 inches just seems too small. I have started puberty very early. My mustache sprouted out when i was around 9. i have a small amount of pubic hair on my testicles and I have 1/4 inch of hair above my penis. I have trimmed it multiple times which leads me to believe it would be around 3 or 4 inches in length if I hadn't. I am 5'4 tall and weigh 130 pounds and am very strong compared to classmates. I can lift about 180 - 200 pounds ( I don't do it often). i found this out when I did heavy lifting because I was helping my friend move. With this information I assume that I am growing too fast. I have also been getting a lot of erections lately. So does this mean that me and my penis are finished growing? Is there a chance that I will grow some more? If so when will I probably finish growing and how big might it get? And also what size do women prefer? Please don't hold back because of my age. I am very mature for my age. I know a lot about sex and things on that subject. Just trust me on that.
