Mr O'Farrell said he inadvertently saved in his ''favourites'' a link titled ''watch two boys break the record for longest kiss''.

The user, who cannot be named for legal reasons, also posted a picture of a youth with his shirt off titled ''an early teen boy completely and utterly adorable. That body is excellent.''

The Sun-Herald inquired about the graphic content at 11.22am on Friday. By 11.46am, Liberal staff had removed the link from Mr O'Farrell's favourites. The other user's Twitter account has since been removed.

Liberal staff said Mr O'Farrell's ''chunky fingers'' were the cause of the gaffe and he had been ''horrified'' to learn of his choice of favourites.

''I've obviously accidentally hit a button on Twitter,'' Mr O'Farrell said in a statement.

''Of course, it wasn't intentional. I use Twitter on my computer, iPad and BlackBerry and, as was revealed during the federal election campaign, my fingers occasionally strike the wrong key.''

Mr O'Farrell was referring to a previous Twitter gaffe in July in which he called Prime Minister Julia Gillard a ''ranga''.
