How can we reform a young man who grew up in a female environment, which affected his masculinity and led him to fall into the abomination of sodomy?

You should advise your friend to stop his shameful behavior, and mention what repels people from the state of effeminate men and their fate. This behavior warrants the curse of its perpetrator, as the Prophet, peace and blessings be upon him, said: "Allah has cursed effeminate men." If he responds, then so be it. Otherwise, abandon him to preserve your religion and your honor.
