Sturgess, of Station Close, Kirby Muxloe, was convicted by a jury unanimously of six counts of indecently assaulting a male, four counts of gross indecency with the same boy and one of causing him actual bodily harm, between 1982 and 1988.
He denied the offences claiming he met the complainant when he was older than 16 and had a friendship that was not sexually motivated.
In an impact statement, the victim said: “What happened in my childhood affected me in many different ways.
“I was deprived of a normal childhood or adolescence and didn’t have a normal sexual awakening.
“I’m not sure what my sexuality is.
“If this hadn’t happened to me I might be happily married with kids and grandchildren.”
He described how the abuse had “skewed” his perception and affected his schooling and career; leaving him with feelings of “low self-worth,” anxiety, panic attacks and taking medication for depression.
He had also previously abused drugs and alcohol to numb out the memories.
In 2011, Sturgess, then of Keightley Road, New Parks, Leicester, was jailed for six years after admitting similar sexual offences upon a boy aged between 13 and 14, in the 1990’s.
Sentencing him on Thursday for the 1980’s offences, Judge Ebraham Mooncey said: “You have done despicable things to him, you corrupted him and he’s tried to take his own life because of what you’ve done to him.
“He’s been living with that burden for a very long time.”
Christopher Johnston, mitigating after the verdicts, said the defendant, who suffered from a heart problem, could expect to serve two thirds of his sentence.
He said: “He may not live out the sentence; it’s a matter of conjecture bearing in mind his ill health.
“I ask Your Honour to afford mercy, because of the possibility he may not see the outside world again.”
Judge Mooncey told the defendant: “I bear in mind what Mr Johnston says about whether you will be able to serve out the whole sentence or not.”
The 16 year jail sentence included an additional one year extension to the licence period.
The defendant was placed on a sexual harm prevention order and his address will be on a police sex offender register for life.
