There is a story about sex and underwear. Sexually-transmitted infections, oral sex and ultrathin, super-stretchy panties are covered.
Panties can be used to protect against infections that can be transmitted from the vagina or anus during oral sex. It is the first time underwear has been used.
The undies are part of an important area of sexual health where few options for protection are used.
The director of the division of infectious diseases at the University of Alabama at Birmingham said that oral sex is not risk-free. She said that the need for protective methods was growing because more adolescents are starting to have sex.
According to the Centers for Disease Control and Prevention, STDs can be transmitted through oral sex. The risk of H.I.V. coming from a vagina through oral sex is very low, according to the C.D.C. The agency said that mouth and throat infections from some types of the human papillomaviruses can lead to oral or neck cancer.
Most people who have oral sex have vaginal or anal sex in the same encounter, so it's hard to know how often they transmit infections.
The F.D.A.'s authorization of this product gives people another option to protect against S.T.I.s during oral sex.
A dental dam is a thin, rectangular sheet of latex that must be held in place with one's hands to form a barrier between the mouth and genitals.
Dental dams, which were originally made of rubber, were designed to isolated teeth during dental procedures. An Australian company, Glyde Health, created a dental dam in the early 1990s that was inspired by concerns of women who have sex with women, an official with the company has said.
Several brands of dental dams have received F.D.A. clearance for protection against sexual disease transmission, but they have not been a hit.
Dr. Marrazzo said that they were extremely unpopular and that there was nothing less sexy than a dental dam.
A 2010 study of 330 Australian women who had sex with women found that only 9.7 percent had ever used a dental dam, and only 2.1 percent had used it often. The report said that dental dams and other safe-sex methods were not used often by women who have sex with women.
Dams are sold online and in sex shops, but are not widely available at pharmacy chains and are more expensive than condoms. The C.D.C. shows how to cut a condom to make a dental dam, but it doesn't seem to be popular.
Chris Barcelos, an assistant professor of women's, gender and sexuality studies at the University, said that dental dams take all the pleasure out of oral sex.
The idea for dam-like undies came to Melanie after she and her husband honeymooned in Mexico. Ms. Cristol was a corporate lawyer when she discovered she had an STD.
When she was teaching about dental dams, people looked at her and she realized how limited the protection options were.
She said she wanted to feel sexy and confident and use something that was made with her body in mind.
She said she named the product Lorals because of the L sound.
The panties are made of latex and have a seal on the inside of the thigh to keep fluids in. The company markets their use for a number of reasons, including when a partner has a beard or has experienced trauma, and they don't want to be exposed.
According to Ms. Cristol, the company responded to customer feedback by decreasing the intensity of the taste, adding more cornstarch and introducing a sheer version.
Ms. Cristol said that the company would meet the more rigorous standards required for F.D.A. authorization, but that it would look similar to its other products.
eroticized protection is something that condom companies have struggled with for a long time.
The F.D.A. said it did not require human clinical trials but Lorals was given authorization after the company submitted extensive documentation about thickness, elasticity, strength and other measures. The F.D.A. gave clearance to two new dental dam companies within the past year.
Some sexual health experts were unsure if the additional option would be popular and needed more information.
There is progress in the field. In recent years, research has changed the way cancer is treated. There are some recent updates.
Chemotherapy is a treatment for cancer. A growing number of patients with breast and lung cancer are avoiding the treatment in favor of other options.
There is leukemia. Two patients with chronic lymphocytic leukemia saw their cancer disappear after receiving a new treatment called CAR T cell therapy. Hope and new mysteries are created by their cases.
The cancer of the shpageal area. In patients with the disease who took part in a large clinical trial, Nivolumab was found to extend survival times. The seventh most common cancer in the world is Esophageal cancer.
He wants to see real-world data from people's actual experience to prove the underwear's ability to block infections.
The F.D.A. clearances and increased product development seem to signal a greater potential market, but I don't see a lot of demand.
Two Lorals customers, whose contact information was provided by the company and who asked to be identified by their first names because of the sensitive subject matter, described various motives for using the underwear.
Wisty, 28, who identifies as pansexual, has had sex with men and women, and uses they/them pronouns.
Wisty, a dancer and energy healer in the Boston area, said they had a common infection that can cause serious inflammatory conditions.
The nurse in Washington State said she saw the panties on TikTok at a time when she and her fianc were struggling to re-engage in oral sex after he had undergone surgery for cancer. After his cancer treatment, oral sex made him feel like he was suffocating, and they had not done it in nearly two years.
It was such a huge thing for him that he enjoyed penetrative sex. She felt that maybe he doesn't have interest in that way anymore without it.
We spent a couple hours looking at it after we ordered the panties. It smells like a candy store and it stretches to kingdom.
The panties worked well, according to Shelly, who said that she could barely feel the panties and that the taste was similar to eating a cookie.
She said that she appreciated the new clearance for protection against infections because they can cause cancer.
She said the sexual experience was important.
