James Bubb, now Gwyn Samuels, has been held in a male prison and will remain there, the court heard.
The 28-year-old from Chesham, Buckinghamshire, was also found guilty of raping a young woman he met online while posing as a 16-year-old girl.
The former special constable was sentenced at Aylesbury Crown Court on Friday to a total of 32 years, made up of 24 years' imprisonment and a further eight years on extended licence.
The 28-year-old identified as male at the time of the offences and was referred to by male pronouns throughout the trial at Amersham Law Courts.
During sentencing, Judge Jonathan Cooper said that since the defendant had transitioned, they should be known by their new identity of Gwyn Samuels.
