Query: Burns like the fires from h-ll!!!

My wife tried Zestra and in about 5 minutes she was on fire. It only got worse when we started to make love. We had to stop and she tried to wash it away - but it still burn for about 1/2 hour. It also began burning me also. In addition, instead of feeling some sort of arousal, it actually had a numbing effect. Definitely would not recommend.
