Yeah, but who doesn't wear a push-up bra? I can almost see how they are useful, although I don't think I'll need one any time soon.
Eric: you're probably attracted to it and don't even realize it, unless it's naked Bambi hunt day. these are actually common, along with the inserts for that voluptuous JLo look.
In some ways the butt sling seems like a better solution than (yikes!) butt implants! (Yes, they exist and they are quite popular in butt-obsessed Brazil). Imagine a nation of women complaining, "my ass is not large enough - I need implants!" Can't we arrange some sort of 'international exchange program'? American women could be proudly display their smaller asses, Brazillian women could show off their curvier asses - it's win/win!
As for the scenario where the guy gets the woman home and she starts removing the slings/pads - if you haven't seen "I'm Gonna Git You Sucka", you really need to....
