I'm sorry to hear that you're experiencing significant pain during sex. Pain in the penis during intercourse can have various causes, including inflammation, infection, injury, or other underlying conditions.

Here are some steps you can take to help alleviate the pain:

• Avoid sexual activity temporarily to allow any irritation or injury to heal.
• Maintain good hygiene to prevent infections.
• Use adequate lubrication during sex to reduce friction and discomfort.
• Consider over-the-counter pain relief such as medications containing aceclofenac and paracetamol, which help reduce pain and inflammation. For example, a medication like Hifenac-P Tablet combines these ingredients and may provide relief. However, this should only be taken under medical supervision and prescription.
• Avoid any harsh soaps or irritants around the genital area.
• Wear loose, breathable clothing to reduce irritation.

Since pain during sex can be a sign of infections, inflammation, or other medical issues, it is important to consult a urologist (a specialist doctor for urinary and male reproductive health). They can perform a thorough examination, identify the cause, and recommend appropriate treatment.

If you experience additional symptoms such as swelling, redness, discharge, fever, or difficulty urinating, seek medical attention promptly.
