Incest, or incest as it is known in the U.S., is not considered taboo in the West.
That has created an environment in which, if a couple wants to have sex, they can do so with impunity.
And that makes it possible for these relationships to thrive and flourish, said Kristin Osterberg, a sex therapist and author of The Best Incest Movies of All Time.
“We are not talking about this in a vacuum,” Osterborg told ABC News.
“This has existed in many cultures, and we are seeing the rise of this subculture, which is largely driven by people who are not really comfortable with consenting adults having sex.”
The fact that some parents and even adults have taken the step to let kids know that having sex with their own kids can be problematic and dangerous does not help anyone.
“I think a lot of people think of it as a new way to be sexually adventurous and not really having to worry about the consequences of doing it,” Ostenberg said.
“But it’s still a way of being intimate with children, which means that it’s about intimacy, it’s not about safety.”
Osterborg said that the taboo surrounding incest is not an issue only for parents and children.
“There are also other forms of sexual behavior, like pornography and fetishization,” she said.
The taboo surrounding anal sex is a little different.
“It’s not as taboo,” Osenberg said, “but there is a sense of fear associated with it, because people don’t want to be seen with it.”
And the taboo around oral sex is another issue.
“You don’t really think about it because it’s taboo,” she added.
“There is a certain way of thinking that the sexual acts are supposed to be performed and the sexual activity itself is supposed to not be performed,” Ozenberg said about the way people think about the act of oral sex.
“I think it’s really about intimacy and it’s also about the ability to have the best sex.
You can’t just go out there and have sex.”
Odenberg said that while the idea of having sex in the privacy of your own home is a good thing, having sex outside your own household isn’t always as great a prospect.
“When you think about having sex, it means you are not being intimate,” she explained.
“So, if you want to have it, it doesn’t mean you’re not being comfortable.”
Osterberg said it’s important to recognize that, even when the parents of a child are in their own home, they are still in control.
“They are responsible for the child, they have to be careful,” she stated.
“And they have some responsibility for the children, who are responsible.
It’s about respecting that.”
Osenberg believes that the best way to help parents and caregivers understand the realities of sex is to be honest and to educate them.
“A lot of times when people have sex they are just trying to make things go their way, to make sure that everything is going right,” she noted.
“The best way of understanding this is to listen to your parents.”ABC News’ Lauren Tarnovsky contributed to this report.
