Hello. Itchy vaginas suck. Believe me I've been there. It sounds to me like you either had an allergic reaction to the silicone or you have a yeast infection. In my late teens and 20's I used to get yeast infections all the time. Sometimes the appearance of the actual yeast didn't show up for a few days. I just had a lot of itching, redness and swelling. Try applying a bag of ice, wrapped in a towel or a cold wash cloth. Either way you should make an appointment with your gyno and get it checked out. Good luck
Yes, I agree, you could be having a reaction to the material of the sex toy. Bummer. Or you could have a yeast infection as well. So, yes. Agree to see your doctor for proper diagnosis and RELIEF! good luck
