Semen allergy

I think I might have one. I always develop sensitivities to things I'm exposed to over long periods of time. I could eat melon every day for a few months and I would probably start reacting to it. It happened with condoms before we were TTC. It happened with milk, wheat, green peppers, tomatoes, soap, tap water, pads and even more! Once I cut them out for a while I can usually put it back into my diet / life as long as I keep exposure limited. Well I didn't tell my husband but almost immediately after sex I started to get super itchy just like with the condom allergy, this morning it now burns. No it is not an STD my husband is job searching now he has his work visa and we haven't been away from each other at all since November and I had my annual exam in January including a full STD work up. We've been TTC since June and I'm seriously worried the exposure to his semen has caused me to develop an allergy. I mean he is big, maybe he just tore me and the friction is causing this but I know what an allergic reaction feels like and it's like the condom fiasco all over again. With the condoms I didn't even think of an allergy and I thought I had an infection, I went to the ER they thought I did too, they shot me full of unnecessary antibiotics and then when I got the results back all negative we had sex again and it happened again! I started rubbing condoms all over my neck and wrist, all different kinds! I reacted to them ALL! All except the non latex one. So I guess he gets to give me a little neck spunk to figure out if I am or not, I really hope I'm not. Welcome to my life.
