Is it permissible for a husband to be sexually intimate with his young, pre-pubescent wife, and is it correct to say that this is wrong and should not be done?

Child marriage occurs in exceptional circumstances if it is in the best interest of the young girl, and only her father may marry her off. There is a difference between merely the marriage contract and consummation. The husband does not consummate the marriage with a young girl until she is physically and psychologically capable of intercourse, which varies according to different environments and times. It should be noted that the legal age for marriage in some Western and Asian countries is still young (13-16 years).
