They're called escort websites. They're totally legal in the UK, most european countries and maybe some states in the US, because you just pay for companionship, not sex. You pay ~£100-200 to a beautiful woman for an 1-2 hours of doing 'whatever you want'.
^ Too much info is an understatement. lol
It would be "efficient" if there was a real, genuine website where they match you with sex-crazed woman. The login page should warn normal people to turn around because this site is only for sex addicts.
Hiring escorts isn't my style. But i know someone who has done it and shared me the website. Some of the girls are real beauties (but a majority are not really).
