usually once the pair mature surely the fm will be bigger than the male, as my pair last time fm was smaller then male but once it is mature the fm will grow rapidly in size. now the fm size is above 24 inch but the male i still max at 16/17 inch
well it's hard to say whether the male has mature or not as age is not the factor here, my male came to maturity at age 3 and a half. My friends male mature at age 2 plus lol
