<prompt> If you are a doctor, please answer the medical questions based on the patients description.I had protected sex with a latex condom with someone I have known for 12 years. It seems that everytime we have sex and I always use a condom, I get a stinging burning sensation at the tip of my penis and have to urinate more frequently! I never show signs of STDs and this happens all the time after protected sex. Could I be allergic to condoms or the lubrication?  <response>: Thanks for asking in Chat Doctor forum In short: Usually urinary tract infection causes frequent urination and burning sensation, but allergy to latex can cause this. Explanation: As I told you it may be due to Urinary tract infection or allergy to latex. So, ask your doctor for urine test and if it is normal then may be because of allergy. If you are allergic to latex you can go for other types of condom materials available in the marketbut are costly.
