Hello! Hope you are doing fine. Seeing that you had past history of itching or irritation to condoms, there may be a possibility that you could be allergic to the latex used in condoms or the spermicide used inside the condoms. This may sometimes result in itching, irritation, burning urination, etc. However, this may not present after a week. If there are any other signs like discharge, redness, soreness, etc. it would be a good idea to consider a visit to the doctor for a physical exam. In the meanwhile, cleaning the area well, maintaining good hygiene, drinking plenty of water, using an anti-histamine like benadryl may help. Generally, having unprotected intercourse is not recommended to prevent the chances of sexually transmitted infections and unwanted pregnancies. Use some form of contraceptive to prevent the same. Hope this helps. Please come back anytime in case of further queries :)
