John Gerard Roddy, of Daly Crescent, Edenballymore, will serve six years in custody and three years on supervised license on his release from prison.
Roddy will be placed on the Sex Offenders Register indefinitely and will be subjected to a Sexual Offences Prevention Order for ten years.
According to court papers, three of the indecent assault charges took place outside of the UK.
The offences took place on dates between July 1, 2007 and December 31, 2012.
Constable Jason McMorris said: “Roddy breached his position of trust in the victim’s life, coercing and manipulating him.
“He took what should have been carefree, happy, teenage years away from him.
“No person, let alone a child, should ever be exploited in this heinous way.
“The victim showed immense courage and bravery to report these crimes to us, which have had a lasting impact on him for many years.
“I hope that his strength and confidence in the Police to conduct a thorough investigation encourages other victims of child abuse to come forward and report.
“We take a robust stance against targeting sex offenders, particularly those who target and abuse children, and will work tirelessly to get take these people off our streets.
“Time is no barrier to reporting offences.
“I would urge anyone who has been victim of a sexual offence at any time to come forward.
“Do not suffer in silence.
“Call 101 or 999 in case of emergency.”Tags:
