Desensitizer is the term for a sexual enhancement product designed to help individuals overcome sexual challenges. These products are usually topical creams or ointments that numb the area to which they are applied. The most common use for desensitizers is to delay ejaculation and to make anal penetration more comfortable.
The use of desensitizers, especially in the case of anal play, is often discouraged for safety reasons. Sex educators advise against using products that reduce sensation and leave participants unable to feel bodily discomfort. Discomfort ordinarily acts as an important signal of damage or injury to the body.
