How long does it take for boa constrictors to reach sexual maturity?

Male Boa Constrictors reach sexual maturity at about 4ft which is usually within 1 1/2 or 2 years of their birth. Females on the other hand reach sexual maturity at about 5ft or 6ft which can take 2-4 years since their birth. The ideal breeding pair would be a 4ft male that it is about 2 years old and a 6ft female that is about 3 or 4 years old.
