Could not get into the OP's link without genuflecting to Google, Facebook, or Apple.
A less starchy source:
https://www.upi.com/Health_News/2022/05/13/FDA-approves-STD-underwear/3371652376179/"Lorals -- which are available as bikinis or shorties -- are made of vanilla-flavored latex about as thin as condom material and form a seal on the inside of the thigh to keep fluids in, developer Melanie Cristol told the New York Times. They are to be used only once, like a condom"
...
"...There's growing need for such protection because more 'teenagers are initiating their first sexual activity with oral sex,' she said."
I thought the gals were using Saran wrap.
Heh:
"Human clinical trials of Lorals were not needed for the FDA's approval, but the agency did require documentation about thickness, elasticity, strength and other measures, as it does with condoms, the Times reported."
That was one of the first things that occurred to me --government testing. My mind is at rest now.
