"They're realistic on the fairytale," she says.

Croydon explores what she calls "low-maintenance relationships" in her new book "Screw the Fairytale: A Modern Girl's Guide to Sex and Love," in which she debunks the traditional ideal of the omnipresent partner. Croydon says she never wants to get married or have kids. (She's also quite familiar with unorthodox dating styles; her first book, "Sugar Daddy Diaries," was about her penchant for older men.)

"You don't have to see someone three to four nights a week to express love," she told CNN over the phone from London.

"In every other aspect of life, we've gone for convenience, independence and where individualism is promoted," she says. "Yet, you have this socially approved model of relationship that you live together."

Croydon says for it to work, the partners' emphasis is still on a genuine relationship, in that there is romance and sparks but "without all the monotony and obligation of a full-time relationship."

Jill Weber, a Virginia-based clinical psychologist and author of"Having Sex, Wanting Intimacy: Why Women Settle for One-Sided Relationships" says this particular style of dating can certainly feel empowering as it allows daters to compartmentalize the relationship.

"It protects you; there's less vulnerability," she says.

Sooner or later, though, she says one or both partners might catch stronger feelings and want something more.
