EXTREME “sex roulette” parties, where one person has HIV and nobody is allowed to wear a condom, are on the rise.
Most of the dangerous orgies are thought to be attended by gay men.
But these racy meetups are said to be commonplace in wealthy circles in Serbia.
Experts claim that it is the thrill of the unknown that drives people to take part in the risky orgies.
Participants have no way of knowing if they will be infected or not.
Dr Josep Mallolas of Hospital Clinic Barcelona said: “There is everything: sex roulette parties, or sex parties you can only attend if you already have HIV.”
The Spanish doctor told el Periodico that the rise of these parties meant that people had lost respect for HIV.
But, revellers can decrease their chances of contracting the incurable virus by taking medication.
Because of this, the orgies are known as ‘blue’ parties.
Psychosexual therapist Kate Morley told HelloU: “Going to sex roulette parties is about the risk, partygoers think the higher the risk, the stronger the thrill.
“In the case of sex parties the intense high is as you combine orgasm with high adrenaline.”
According to a stripper named Tijana, the unusual and very risky parties came from Serbia.
She said that the orgies were known as Serbian sex roulette, a play on Russian roulette.
Tijana said: “I can see that everyone is talking about sex parties now, but in fact they have been common for a long time even here in Serbia.
“In fact what really shocked me was this bizarre variation that seems popular for extreme sex. People who turn up for the party wear masks, and one of them has HIV.
“The wealthy organise these sex parties for other rich people.
“The real kick for these people is apparently the risk that they might be the one having sex with the HIV-infected partner.”
