As someone who has been having way to much sex, drunk sex, rough sex, and mostly really fucking sweaty sex (it's still 90 degrees here in LA), I could totally see this eliminating the ingrown hair / friction burn on my partner and my upper-nether-regions. Everything about my partner and I are uber-compatible except for my trim job and his trim job.
Friction. Fuck it. Also, the idea of actually wearing this...fuck it.
"So you can avoid awkward...." while literally showing a woman taking off his pants to reveal a weird-latex-flesh-colored-half-thong.
I do appreciate that the horrible 3D animator paid careful attention to the sideboob though. NAILED IT!
Serious point -- I think other people in this thread have brought up a very valid use case. If you notice though, none of the site's marketing copy relays these points except for some discreet information in the FAQ and external links covering the spread of herpes, etc. If you wonder why this is, it has to do with how people self-identify, especially online. Even though typically including references to the self (Self-Reference Effect) increases recall of information and therefore is a good thing in marketing copy, it works the opposite in cases like this where the situation / product / benefits / solutions are associated with something shameful / negative / private. Basically, even people with herpes don't self-identify as someone with herpes. They identify as someone who likes to run, or have awesome sex, or whatever. In cases like these, including prominent marketing copy that requires the user to self-identify as someone with herpes actually has a negative effect on a user's recall and motivation. It's better to keep it discreet and let the person come to the realization that this product is a solution for their situation on their own instead of spelling it out for them.
