Is it normal to have a itching feeling after taking whey protein?

Anonymous
Hello, I bought an optimum nutrition whey 100% vanilla French cream flavor and I am afraid that is is fake. I don't have any allergy from milk or from any food. I eat ice cream vanilla and vanilla other food without any problem, lactose anything. The first time I drunk a scoop of this "protein" I got a pimple lower then the abs around the dick area and one small in the chest.
The next day I splited one scoop half before and half after my workout. Again I had itching feeling and a feeling like the pimple would break up, but no pimple showed up. (I had also some itching on the dick too and small burning...)

I want to know if those are normal with any protein supplements or only with fake supplements with testosterone and other shitty chemicals?

PS: As you can note, it is my first time that I buy supplements and I can't compare the taste or effects with any previous whey protein.
