[/INST] Hello, Itchy penis after intercourse can happen due to Chat Doctor.  If this is the case, your symptoms should improve within a couple of days of abstaining from sex. You can use lukewarm saline water to wash the affected area three or four times a day. If the symptoms do not improve in two days, do consult a doctor for physical investigation. Hope I have answered your query. Let me know if I can assist you further.  </s>
