I love this product and have been using it for a long time. The trick is to rub some on the tip, give it a few minutes to numb, and then go to town! It does not stain or smell or sting the skin. I have had very good results with it and will continue to use it! PS: it does not numb to the point of not being able to feel, but it numbs just enough to make it last longer and enjoyable for both parties.
