There's a couple of sites that spe******e in kinky rubber talk- the best I know is the IAR- International Association of Rubberists- it might be worth a look.

I'd be inclined to think if you leave it out hanging around, the chemicals will dissapate somewhat- another trick is to stick it down her/your pants for a few hours, that works with leather cuffs & so forth sometimes- something about the body oils mingling.....

My girl had this problem too, it just went away to some extent after a while.

Edit- Hmm, we seem to have some posting probs today- or maybe I'm being censored

Substitute s p e c i a l i s e for the first funny word, & rubberist for the second.
