QUOTE(xrrat @ Mar 23 2008, 04:18 PM) [snapback]86088[/snapback] Hi lycrafan, Indeed, I made some quite similar (not so enjoyable) experiences. Mostly with latex or what I believed to be latex. I haven't done any medical testing (and you bet I -- xrrat -- would never do a test intended for cats ). But because the burning occurred again and again always with the same toys or e.g. with condoms I called this "allergic", at least in my own words. And eventually I got rid of the bad toys. Strangely, I never had problems with latex condoms on my cock (but I never used them much either). So, some stuff, and I guess it is (mostly) latex, burns, feels itchy or dry no matter how much lube I use, seems to stick to my intestine, or just plain hurts. I never saw a reaction or irritation of my skin. However, the feeling was bad enough to quickly remove whatever caused it. I have had no problems with silicone toys, rubber and this harder stuff they use for dildos and plugs (PVC?), nor metal or glass, of course. BTW, I never tried Crisco. And I never tried latex free condoms on toys. One huge problem we are all facing is that we often do not know what the (manufactured) toys are made of. And even if the package says rubber or silicone, in general, you never get to know what they use as plasticizer ( see http://en.wikipedia.org/wiki/Plasticizer and http://en.wikipedia.org/wiki/Latex_allergy ). Sometimes during heavier play I can feel some burn from some water-soluble lubes (like they had some vinegar or alcohol ingredients) Hello Gays I have the same problem,for me water lub for example ky is like samthing like vinegar,silikon toys the same.Same toys are neutral(the falcon toys,i'm not sure but they are made from rubber,but they have a minus they are hard).The best lube for me are natural vaseline or nivea cream or feminum(Polish water gel for woman)
