SEX offender Leo Kiss has been locked up for four years after targeting a young woman he fancied in the street and pinning her against a wall.
He left the victim "traumatised" and "terrified" after approaching her for sex and later lying in wait for her outside a house, a court heard.
Kiss, 18, of Blundell Avenue, Cleethorpes, denied sexual assault and attempted rape but was convicted by a jury.
He admitted separate matters of burglary and theft.
Judge Mark Bury told Grimsby Crown Court that the young woman was walking her dog in the early hours on September 25 when she encountered Kiss.
He made sexually suggestive comments to her, saying she was "fit" and that he would like to have sex with her.
He touched her bottom in a suggestive way. Kiss followed her to her friend's home and waited for her in a driveway opposite the house.
He later approached her again, walked by her side and again asked her for sex.
He pulled her on a parking area in Grimsby, took her behind a parked car and pinned her against a wall.
Kiss touched her intimately and put his hand down her leggings bottoms.
"She was traumatised and really frightened and terrified," said Judge Bury.
The victim later revealed the extent of her trauma.
"I have never been so scared in my life," she said.
She later ran off to a nearby fast food restaurant, where the manager helped her and called the police. Kiss later denied it was him and said he was drunk.
"This was a very distressing incident for her," Judge Bury told the court.
"She says she is reluctant to go out and is a bag of nerves."
In a separate incident, Kiss burgled a house in Park Street, Cleethorpes, on January 29 and took an iPod.
He also stole two treasured diamond rings and a gold chain from the home of Maureen Howarth, in Brereton Avenue, Cleethorpes, on February 19.
He had been a regular visitor there, the court heard.
Craig Lowe, mitigating, told the court that Kiss had only two previous matters of shoplifting on his record.
"He will find it difficult in custody and particularly difficult being away from his family," said Mr Lowe.
The court heard he came from a supportive and close family and had used his time in custody productively by improving his literacy and numeracy skills.
Kiss was ordered to register as a sex offender for life.
