This sounds to me like it could be genital warts. I don't want to preach to you - but please realise that all it takes it one brief encounter to contract an std. If this is your first experience using latex condoms, it certainly could be an allergy but the fact that it is only on one side of your vagina is worrying.
Obviously we are not doctors, but you need to be prepared for the possibility that you have herpes or warts, and may have it for the rest of your life. We have all had careless moments in our past where we weren't as responsible as we should have been, but please use this experience to think more about the choices you make in the future.
It's good you are going to the Dr.
Yes, you could have a latex allergy. There are condoms that are non-latex that you could try and see if that makes a difference.
Have you tried to hold something with latex to see if you get a reaction? Like hold a balloon and see if you get irritated on your hands or arms.
I don't know anything about herpies. your Dr. will be able to tell you with that. good luck and hope you feel better.
it cant be that ur allergic to latex...because if you were...you wouldnt have started gettin irritated there after he DIDNT use a condom...im not sure what the problem is...but u definetly need to see a doctor.
