Peter Laskaris, who operates two brothels in Vienna, said that although life-like dolls from Japan 'cost up to 7,000 euros ($11,300)' it is 'obviously a trendy sex fetish' which other brothels must also follow.
Sex industry experts estimate that people with a fetish for sex dolls is are an increasingly growing group, and that they expect more dolls to be made available by brothels, the MailOnline reported.
Psychologist Gerti Senger explained why some men are more interested in sleeping with Fanny instead of a real woman.
Senger said: "First, the man can do anything with the doll. Second, every intention is turned off, which can be a factor with a prostitute."
Yet Senger, who is a co-chair at the Austrian Society for Sexual Research (OeGS), said that she was shocked by Fanny being more popular than real prostitutes and called it 'a real autistic tendency'.
