A couple have sex while fellow reality TV contestants watch and cheer - the incident this month. LIBBY PURVES says even mating animals behave with more dignity

LIBBY PURVES: Reality TV sex is nothing more than pointless, exhibitionist telly: randy, gullible kids lured to coupling for the sake of ratings. Some commentators will describe the behaviour on the shows as 'animal' but wildlife has more dignity. Partly because animals do it out of a straightforward biological instinct to produce offspring, and partly because - being tortoises or sealions - they don't talk about it at length on the Loose Women TV show afterwards.
