Seems like an unexploited market niche. Scent is so much a part of good sex that the smell of plasticizer would be a turnoff, or at least missing a big part of the excitement.
Any suggestions?
Gotta be this stuff:
You don’t want that annoying plasticky “squeak, squeak, squeak,” when you are in the vinegars! 
But, seriously folks…
Real, live Asian girls squeak too. It takes some getting used to.
