The 70-year old is accused of 11 counts of indecent assault against seven girls and women, which he denies.
Giving evidence at Southwark Crown Court, Mr Clifford denied ever meeting many of the women, and dismissed their claims as completely untrue.
One alleged victim claims she met him on holiday in Torremolinos, Spain, in 1977, and he kept in touch with her family, coming to her house and taking her out in his car after she returned to the UK, where he would persuade her to perform sexual acts on him.
But under questioning from his defence barrister, Richard Horwell QC, Mr Clifford said: "That's totally and utterly untrue.
"It just doesn't make any sense at all.
"If I wanted to have a relationship with someone, there were hotels, there were places where I had already been in relationships.
"It's just crazy, it's a load of lies."
Asked if he was ever sexually interested in a 15-year-old in 1977 or 1978, he said: "No, it wasn't me."
The trial was adjourned until today.
