A father of two young children spent weeks engaged in highly sexual communications with an undercover police officer posing as a 12-year-old girl, a court has heard.
Huw Jenkins had initiated contact with the girl after seeing her profile on social media.
He then went on to send a series of disgusting messages to the girl, including ones where he boasted about the size of his penis.
A judge at Swansea Crown Court asked the 39-year-old to think about how he would have felt had he found somebody saying such things to one of his young children.
Helen Randall, prosecuting, said in September last year Jenkins made contact with someone who appeared to a 12-year-old girl on the messaging Snapchat.
The court heard the profile was in fact being run by an "undercover police operative".
Miss Randall said the person behind the profile made it clear to Jenkins the "girl" was only 12, but over the following weeks the defendant sent a series of highly sexual messages.
In some of the communications he asked for photographs of the girl, while in others suggested she perform sexual acts on herself.
Jenkins also sent a photograph of his partially-opened trouser fly with the message "It might pop out and say hello", while in another message he asked he if she "liked big ones" and said "I love getting my big c*** out".
The defendant was arrested at his home address on October 19 after some four weeks of contact.
In his interview he denied getting any sexual gratification from the exchanges, and said he did it because he was "very bored at work".
Jenkins, of Heol Las Close, Birchgrove, Swansea, had previously pleaded guilty to attempted sexual communication with a child when he appeared in the dock for sentencing.
The court heard he has no previous convictions.
Ian Ibrahim, for Jenkins, said it was accepted the defendant had engaged in "grubby, nasty, unattractive offences".
He said his client was a dad-of-two with a strong work ethic who had worked for construction company Dawnus as well, in latter years, for house builder Barratt.
The barrister said Jenkins and his wife had separated following his arrest, and he was a man who "has lost so much".
Judge Geraint Walters told Jenkins the conversations he had held with someone he believed to be a 12-year-old girl were "disgusting", and asked him to consider how he would feel if a man had engaged in such behaviour with one of his young children.
Giving the defendant a one-third discount for his guilty plea he made him the subject of a two-year community order with a rehabilitation course, and ordered him to complete 100 hours of unpaid work.
Jenkins will be a registered sex offender for the next five years, and was made the subject of a sexual harm prevention order for the same period.
