Britain's most prolific mistress Gweneth Lee has told how she is juggling three affairs with married men for Valentine's Day.
The 47-year-old is dating an international jeweller, a high-flying stockbroker and a powerful banker at the same time.
She will spend different nights with all three over the next two weeks in the build-up to the most romantic day of the year.
But she will be all alone on February 14th because her three lovers will be with their wives.
Business consultant Gweneth, of Chelsea, West London, said: "Valentine's is the best time of year to be a mistress because you are lavished with sex and presents.
"Married men may make a fuss of their wives on February 14th but they spend a lot more money on their mistresses.
"In my experience the gift to the mistress tends to cost double whatever they give to the wife, and it is far sexier.
"I've been a wife on Valentine's Day, when I was married to my late oil executive husband, and all I can say is that being a mistress is a lot more fun."
All three of Gweneth's lovers are aware that she is seeing them on a 'non-exclusive' basis and that they will be sharing her with other married men in the run-up to Valentine's.
It means she has been busy juggling her diary to make sure that her lovers get the attention they deserve.
She met all three men on IllicitEncounters.com, Britain's leading dating website for married people.
It attracts a wealthy clientele and the average annual income of male members is £52,000 - around double the national average.
It boasts many high-flying multi-millionaires in its client base.
Affair number 1 - the international jeweller
Gweneth said: "This will probably be the most fun of the three dates because my lover is a real party animal.
"But before we crack open the champagne we'll head off to Bond Street in London for a shopping trip.
"He is an international jeweller with quite exquisite taste and he obviously has the connections to pick the very finest pieces at the very best prices. I have been seeing him on and off for a few years and in the past he has bought me the most beautiful pearls and a gorgeous necklace from Tiffany. I cannot wait to see what we will choose this year.
"After that, it will be back to one of his favourite hotels - Claridge's or the Savoy. He is in London about six times a year and I am his girl in the capital. I am pretty sure that he has my equivalents in Paris, Milan, New York and some of the other great capitals of the world where he travels on business.
"He is in his 50s and enjoys a good sex life with his wife. But he is very, very highly sexed and enjoys having discreet affairs when he is away on business. I've booked him in for early February - my first Valentine's treat!"
Affair number 2 - the high-flying stockbroker
Gweneth said: "He is in his 40s and lives in the Home Counties with his wife and three children. The kids are all still at school and his wife's energies go into bringing them up - leaving little time for passion with her husband. That is where I come in.
"He stays at their flat in the City around three times a week. He loves lingerie so I am looking forward to lots of beautiful Agent Provocateur as a present. The one condition being that I wear every piece while we enjoy oysters, champagne and lots of delicious strawberries. It is going to be an exhausting night."
Affair number 3 - the powerful banker
Gweneth said: "I don't know what it is about the City and sex but most of my married lovers have worked around the Square Mile.
"My third Valentine's lover is the kinkiest of the lot. He is like my very own Christian Grey from Fifty Shades of Grey and likes to set up his own Red Room of Pain just for me with all sorts of floggers, spankers and riding crops. You won't be surprised to learn that one of his weekend hobbies is hunting. He is so highly sexed that our little trysts often start in the restaurant before we head back to the hotel. He has been in the Mile High Club with several different women and is always look at ways to spice up his high-pressured life.
"He is also married with teenage children. He is devoted to his wife but no woman would be able to keep up with his sex drive. He sees me and several other women in London. We know that we are never going to keep him on an exclusive basis because he is absolutely gorgeous, easily the best-looking of my three lovers."
Gweneth feels no guilt over her affairs - and says she is helping to keep their marriages together.
She explained: "The sad truth is that monogamy is unnatural. Who decided that it was good idea to commit to one person in your 20s or 30s and then stay with them for the next 50 years? Where is the fun in that? Inevitably the sex is going to go stale.
"Go out on Valentine's night and you will see thousands of couples staring at each other vacantly over dinner. They have very little in common, sex has become a routine and they have stayed together for the sake of the kids or because it is too expensive to divorce.
"They could get a new lease of life by signing up to a site like IllicitEncounters.com, where like-minded married people can date each other, safe in the knowledge that they will have some fun but no one is going to get hurt and start demanding a divorce."
llicitEncounters.com spokesman Christian Grant said Gweneth was typical of the women on the site which has a 45-55 female/male split.
He said that Valentine's was one of the busiest times of the year for IllicitEncounters.com.
"Valentine's may be the most romantic day of the year but it can also brutally expose the weaknesses in a relationship and the lack of sex, intimacy and fun," he said.
"Lots of people use Valentine's to reassess their lives and make a decisive change by signing up to a site like ours.
"We are an outlet for men and women who would have an affair whether we were there or not. In coming to us, they can be assured of meeting a like-minded partner seeking some added excitement in their life who doesn't want to upset things at home."
More than one million people have registered with the site since it started in 2003 and the highest proportion of members are wealthy people in London and the Home Counties.
