S traight men have long had a fascination with lesbianism. Tap the word into Google and you can see the range of porn available, from "Naughty girls sharing their Huge Toy", to "Vicky and Nea need no men". I have lost count of the number of times men have asked me what I "do in bed". They can't imagine sex without a penis being around somewhere, which is presumably why so many lesbian-fanciers offer to help out in the bedroom. Once, on my way home from a party with a girlfriend, I was asked by a passing motorist if we would consider putting on a sex show for him in the back of his car while he watched. Our state of inebriation was such that all he would have got for his money was a bit of snoring possibly interrupted by puking, so we declined out of courtesy.
