<s>[INST] For the past day I have masturbated a lot and I just noticed that my penis started hurting. As I took a look at it I noticed that my skin was irritated from masturbating. What can I do to get rid of the pain and is this from masturbating too much or is it because that I use shampoo as a lubricant? [/INST] Degree understand your concerns went through your details.
