Allergic to silicone? I've never heard of such a case. It's supposed to be a hypoallergenic material.....
technically it is, however the polymers and elastomers that the silicone toys are made with can sometimes cause allergic reactions. these types of reactions are extremely rare but do occur even with medical grade silicone (cause they are still made in much the same way as a dildo, just for different purposes and clean room environments).
yeah... odd no?
