Why is my girlfriend allergic to me? Is it possible?

Hi there. So I have a crazy problem. My girlfriend is allergic to my saliva and semen. She has gone to a dermatologist and had a full back allergy test and was not allergic to most of the things tested for and the ones she was positive for it was a mild reaction. She is always fine when she isnt around me but they moment I kiss her her lips get rashy and now she is getting a severe reaction to my semen. Where ever she comes in contact to it she gets hives and swells up. I am a scientist and have done a number of tests and can say with 100% confidence that her reactions are to something to do with my secretions. Very recently she has been getting hives all over her legs during intercourse simply by me touching them with my legs. Her reactions are seemingly getting worse.
Because of the severity of her reactions we had no choice but to call off our relationship. Needlesstosay it's pretty tragic and I would very much like to know if anyone has any medical experience with this situation.

Any advice/information would be much appreciated

Wow are you sure it isn't something you eat that is in your secretions and not the actual secretion, you could try changing your diet omit something or a few things perhaps and try again.  I have extremely sensitive skin and if my boyfriend eats banana's I get a reaction to his saliva and semen.  However if he doesn't eat banana's I have no reaction to him.  So good luck.

Hello. Ive tried a number of things, including eating nothing but fruit for 24hrs. She still reacted. How did you find out that he was allergic to bananas?

No I'm allergic to bananas.  We just started keeping track of what he ate when I had the reactions and the common thing was bananas!  I think it can take more then 24 hours.  We tried a week without them and then he ate 1 again and I had a reaction to his semen again.  But my reaction wasn't hives persay it was like a burning feeling and my skin went bright reddish like a sunburn.  It is very sad to end your relationship over that!  I hope you can figure out what she's allergic to in your secretions and you can have a good relationship with her!  Good luck.
