I'm Concerned About the Skin on My Penis
Using dish soap on any part of the body, but especially in the genital area, could easily irritate and dry out the skin. TeenHealthFX is not sure whether you were using the dish soap to clean your penis or as a kind of lubricant to masturbate. If you were using it to clean your penis, many doctors recommend washing the genital area primarily with warm water and use a gentle soap sparingly if needed. If you were using the soap as a type of lubricant for masturbation, it would be much better to use a lubricant that is designed for that – something you could buy at the pharmacy or drug store.
Because TeenHealthFX cannot make any diagnoses or treatment recommendations over the web, and given the concerns you have about the color of your penis and the lack of sensitivity to the touch, it would be best for you to meet with your primary care physician or an adolescent medicine specialist to get it checked out. If you don't have a doctor and live in northern New Jersey, you can call the Adolescent/Young Adult Center for Health at 973-971-5199 for an appointment with an adolescent medicine specialist or contact your local teen health center or Planned Parenthood. You can also contact your insurance company for a list of in-network providers.
