Used a new kind of condom with lubricant already on it and i now am red and itchy and swollen. a yeast infection or reaction. have never used lube.

Prob yeast: Could be either although yeast more likely. try takin over the counter yeast meds and avoid that particular condom~

Allergic Reaction: It sounds like allergic reaction. Try Benadryl (diphenhydramine) and avoid that lube.

Yeast vs Allergy: It sounds like that lubricant did not agree with you. You should see a doctor, PCP or urgent care, for complete evaluation and treatment. In the meantime, avoid sex and any lubricants or condoms.
