Hello! Thanks for using healthcaremagic.com I read carefully your question and understand your concern. I think you had allergic to the latex condom spermicide. Perhaps you are allergic to the latex condom, one of the most common allergic reactions caused by sexual intercourse. Although they say it affects only 1% of people, you can actually develop the allergy or sensitivity to the condom with the progressive contact with the latex or the material from which the condom is made - and / or the lubricants and spermicides it contains. Generally, the symptoms of the allergy to the condom appear within a few minutes of penetration, but then they may get worse. In cases of irritation, hives and more severe dermatitis occur hours later. For example, the formation of blisters on the skin that has been in contact with the latex is common. I see similar cases amongst young people who visit my clinic. In the first meeting, I advise my patients to avoid using latex condoms to prevent these symptoms, but obviously always remembering the important premise of practicing safe sex. If you are sensitive or allergic to latex, you can resort to polyurethane condoms or animal skin condoms. Polyurethane condoms work in the same way as latex condoms: they offer protection against pregnancy and prevent sexually transmitted diseases. Animal skin condoms, however, do not provide protection against STDs. While commonly allergic to condoms is not too serious, exposing yourself to such symptoms over and over again can be both annoying and harmful and can compromise not only your sex life but your overall health. And here the situation can be worse. So the best advice I can give you is to consult with your urologist properly diagnose your case, analyze what risks you have been exposed to in contact with latex condoms, and of course know what other contraceptive methods you can use that are harmless and comfortable. Kind regards, Dr. Oscar Martinez
