London, May 12 : A new survey has revealed that nearly three-quarters of Brit adults make use of Internet chatrooms and social network sites to find no-strings sex.

The survey led by Five's hit series Generation Sex has shown that 86 per cent of the adults admitted to sending dirty text messages, while 74 per cent have had phone sex.

The survey also revealed that more than half of over-18s have filmed themselves making love.

"Our survey highlights liberal attitudes," The Sun quoted a spokesman, as saying.

"Nearly half of adults admit having had a threesome and 82 per cent would consider an invite to an orgy," the spokesman added.
