What factors other than genetics determine penis size?

I was an extremely anxious kid and my dick is nine and a halfinches. I had a shitty diet filled with sweets and junk food because I'm black. I am also a virgin because I live in a neighborhood with no singe females.

>9.5"

I'm still a virgin at 23 because I had no social skills. Mom didn't want me corrupted. I only learned how read body language as an adult

I'm barely under 6 though. Not horrible
