The author, Aurora Della Croix - for protection from and out of concern for the repercussions of this book - wrote under a pseudonym. He earned a degree in political science and English literature from Lehman College, City University of New York, a master's in non-profit management, and is working on an online doctorate through Rushmore University. He said that it was necessary for women to be informed, not only with anecdotes, but for their own survival, as many Black women need to be protected from the spread of HIV, from men having sex with other men.

"The ideal man won't tell his woman about this, but as an out gay man, I feel that I have to tell women about the Down-Low Brother or DLB men," the author said.

The title, Gullible Girl, published in September 2008, not only describes the easy, naïve manner of many women, but is intended to empower them, causing a transformation from ignorance to knowledge.

"There are too many men who are hiding and there are many women who are gullible to the wiles or devices of men, who would prey and exploit that weakness. I am concerned about the immediate women folk in my life, and by extension, the larger female population. Women are the backbone of every society, so someone has to write something to give women the information, tools and devices to protect themselves," he said.

The use of Gagging, said the author, who also wrote, directed and produced the off-Broadway play, The Thin Line in 1989, which documented a confused period in his life, and which was performed at the Sanford Meisner Theater in New York City; is a gay term which means to render speechless or shocked into speechlessness. The reason for including it in the title is that a DLB is like a spider, spinning a web of lies to his woman, giving the impression and convincing her he's in a heterosexual relationship, and is intended to shock men into opening up to accepting discussion with their women about whether or not they really do like women.

Generally, a person cannot tell whether a man is gay, having sex with another man, or on the down-low, he said. Women need to know and need to communicate with men, asking simple questions, such as: Is there someone else, a woman or a man?
According to the author, women, also need to modify their relationships with men, where the traditional model of relationships that is based on religious precepts is not working and there is an urgent call to redefine each relationship.

The difference between his book and other DLB books is that those books share stories or anecdotes of the DLB after the deception of the relationship has been exposed; Gullible Girl provides the tools to recognize the signs and patterns of behavior, attitude and actions, and how to be prepared before a fragmenting relationship reaches point critical, the "blow-up." While he doesn't feel he's betraying his gender, he also doesn't think he's exposing or "blowing-up" the DLB men, but as a concerned man and someone who recognizes the rights of freedom of speech, he declares that when he sees something that needs to be spoken about and as long as he has the resources, he would address the issue.

At the beginning of his 82-page book, the author issues a disclaimer where he states that the contents of the book are based on his views and experiences, and is neither based on statistical information nor social or psychological studies, unless specifically noted. The book is divided into five distinct sections: Men as Sexual Beings, examining male sexuality; Mythbusters, examining and de-mythifying men; Discovery Process, defensiveness and avoidance; Profiles, recognizing the contemporary male social stereotypes; Your Man's Penis is on the Rise and so is HIV/AIDS, factual presentation of HIV and AIDS; and a poem written by the author and a Glossary of terms.

While he expects negative feedback from many DLB, especially those in the Black community, and likely from many rappers and hip hopers, because the book describes stereotypical men: the homo-thug, the metrosexual, the hustler, the player, and the "holy man," those church men who have sex with other men, and who after arriving at an orgasm would use the Bible to quote scripture in an attempt to expiate their just concluded action. He also addresses the issue that men are terrible liars, spinning webs and devising ways to protect themselves. Women need to catch and recognize the lies.

"A woman just has to sit back and observe her man's behavior, because eventually, he would trip up," he said.

Many women who engage in relationships with men see the opposite gender as "all man," have sex with them, hoping for different results, while ignoring the issue of the possible bi-sexuality or DLB, the author said. Many women are caught in peer or family pressure to find a man, or are caught up in the social hype and expectations about men, but in the book, he advises women not to be paranoid, instead to ensure they do possess the tools: be more observant and aware of their surroundings and their mates, and to remember that observation does not necessarily take the romance from the relationship.

This is not about giving up on love, he adds, it is about advising women to first of all love themselves, and if a woman finds she is falling in love with a man, that she sees him as her soul partner, the woman needs to take a step back and look at her feelings, determining what is imaginary and what is real, by examining her health and the HIV status of her male partner. The main message of the book, he added, is that it encourages communication, women knowing themselves, being safe and being clear about what they want versus what they need.

While trust in a relationship is certainly affected by the increased scrutiny, the author believes that no one should ever invest total and complete trust in someone.

"I'm not saying a woman should not trust her man, but she should not to take the man always at his word. With a woman's health in question, especially with the transmission of HIV, open communication channels enhance the trust in the relationship. Today, everyone entering a relationship should think that the other is HIV-positive," he said.

In the book, the author advises women should look at male bonding rituals and constructions: when a man is going out with another male friend more than once a week and she hasn't ever met that friend, that is a flag to make a mental note; women need to be aware of the cover her man creates when he introduces her to his close friend, buddy or "boi," and she should pay attention to that relationship between her man and his "boi." Men who want to hide their DLB status usually are connected with similar men, cloaking themselves as undetectable or "un-clockable."

"Watch out, your man and his "boi" may both have girlfriends as covers for the relationship with each other; pay attention to the responses he provides when you ask about his "boi." I'm not telling women to go and spy on their man, but to pay attention, for example, if he constantly receives cell phone calls which he doesn't acknowledge when he's with you, he may be hiding something; he may be having a relationship with someone else, and while it could be another woman, it could also be a man. Women should always trust their gut instinct and follow it," the author advised.

The author suggests that another sign that a woman's male partner may be having a relationship with another man is that the he is not requesting she perform oral sex on him. She should take it as a sign and be aware he may be receiving it from a man. The author claims that studies have demonstrated that the male biological jaw muscle structure was designed for suctioning as in the performance of fellatio, but is different in women who are not as naturally equipped. Those women, he said, who do not like to perform oral sex on their male partners, do not know how or think of it as nasty, need to know how to do it, as men derive significant amounts of pleasure from receiving oral sex. There are classes available for women, and if a woman doesn't make an effort to satisfy her man, then she would likely loose him to another man.

While a woman should know how to provide pleasure to her man's body, from head to toe, because that's what he wants, she should also be aware that if he wants to go and be with another man, there is nothing she could do about it.

At the back of the book, the author published a poem, called Precious Stone, written for women and which has been performed by various women. While the book is not really written for men, he said, if a man should pick it up, hopefully it would spark a discussion between a man and a woman about his sexual preferences.
