During Ejaculation Inside Me, I Feel A Tingling Inside The Vaginal Walls. Then Feel To Urinate. Have Fishy Odor. Suggestions?

Hi, during sex with my husband (in particular as he ejaculates), I experience tingling inside my vaginal walls. After he pulls out, I immediately urinate. However on the next day, I have a fishy odor and blisters begin to form on the inside of my vaginal walls. I've been tested for every STD two and three times each; the tissue swabs have even been sent to the CDC. I never experienced this with my previous husband or other sexual relations. Even if I ask my husband to pull out before ejaculation, whatever fluids he deposits inside of me irritate me to the form of blisters and that fishy odor I can't stand. After a few days the blisters clear up and the odor goes away. The specialist who treated me last prescribed Fluconazole tablets (150 mg) once every other day for 6 months - explaining I had a severe yeast infection. After the treatment, and receiving a clean bill of health I still experience(d) the aforementioned symptoms. My husband has been tested for STDs as well and no one seems to be able to pinpoint why I experience what I call allergic reactions to my husband's bodily fluids. I am allergic to latex and found this out early on. When I was single, my partner used lambskin condoms. I did try the latex condom years ago which is how I learned of my allergy. The symptoms after sex with my husband are similar to the symptoms from my latex allergy. Can you help?
