Weather, affordability and sight-seeing and shopping opportunities are all definitive factors when planning a vacation, but have you ever considered the level of a city’s sex-positiveness?

If you’re on the hunt for a sex-fuelled sabbatical and need some direction, you’re in luck. Adult mobile app portfolio Lazeeva has put in a ton of work and consulted an assemblage of permissable research to determine which cities around the world are the most “sex-positive,” which Lazeeva describes as “having or promoting an open, tolerant, or progressive attitude towards sex.”

To quantify how sexual a city is, Lazeeva’s team began by researching 10 critical factors in over 200 cities from around the world. These components include: gender equality, LGBT friendliness, access to contraception, swinger-friendliness, adult entertainment, porn consumption, sex toy consumption, sexual satisfaction, willingness to experiment and sexual activeness.

After attributing a rank for each category, Lazeeva used in-house data and combined it with research from the UN, the World Bank, as well as various listings in each city for sex and sexual health resources available for swingers, LGBTQ groups and charities, to give a comprehensive and decidedly fair score to each city studied. They then crafted a near-encyclopedic ranking of the 100 most sex positive cities worth the stamp in your passport. We’ve narrowed it down to the top 10.

The most sex-positive city in the world is–drum roll, please…–Paris, France! Which proved to be exceptionally sexually-active and gay-friendly. The city of love also boasts quite a thriving swingers scene.

In a very close second comes Rio de Janeiro, Brazil, which received top scores in sexual activeness and willingness to experiment. However, their paltry score in gender equality brought the overall average down significantly.

London, England came third, thanks, in great part, to their thriving adult entertainment scene and praiseworthy scores in LGBT friendliness.

The first American entry is none other than Los Angeles, USA, ranking fourth overall. The porn capital recieved top scored in–you guessed it–porn consumption, as well as very imposing scores in its willingness to experiment sexaully. We should add that both Playboy HQ and the Playboy Mansion are located here and, in case you couldn’t tell, we love us some sex.

If you like to swing, you might want to book a trip to Berlin, Germany, which ranks fifth. In addition to a prosperous swingers scene, they also received soaring scores in adult entertainment. But be warned: Berlin has horrible access to contraception. So bring rubbers.

New York City comes sixth. The Big Apple was impressive across the board, but boasted exceptionally high scores in porn and remarkably low scores in gender equality, which evened themselves out.

In seventh comes Sao Paulo, Brazil, who earned the highest possible score in sex toy consumption and a commendable score in their willingness to experiment. No doubt a winning combination for the sexually dauntless.

Vegas, baby! Coming in eighth overall, sin city proved prolific in–duh–adult entertainment and–double duh–its swingers score.

Ibiza, Spain, is known to be a party place, so it makes perfect sense that they’re sexually progressive. That is, if you’re a man. Gender equality in Ibiza, however, proved upsetting.

Bookending the top 10 is one I’m willing many of us predicted would be higher on the list. This is, of course, Amsterdam in the Netherlands. Surprising, considering the city is host to the world’s only (legal) Red Light District and lax laws around drug use.

Understandably, if you didn’t want to book a nine-hour flight in the interest of sexual exploits, a number of American cities broke the top 10, most of which are located across the map, making them a fun little road trip. These sex-positive American cities include: San Francisco (11th), Miami (14th), Austin (19th), Chicago (25th), Seattle (35th), Portland (36th) and Boston (49th).
