Please help me. [/INST] Hello, The penile head is naturally sensitive and that is the reason you get the pleasure when you have sexual intercourse. You are feeling irritation and pain on the penis head because you are touching it bare.  When you have sexual intercourse, vagina will be filled with lubricating liquids. In that case, you will never feel irritation or pain. Instead, you will feel more pleasure. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.  V.
