I questioned if I should share this, but if I could help someone else, I should get over it!
I am highly allergic/reactive to my husbands semen.
I suspected this last year and told the doc. he recommended using condoms, we did for awhile and just kind of stopped.  My husband had a vasectomy 18 years ago.  So condoms are not necessary or appreciated!!
I have altered my diet, my environment, my personal products and totally overlooked the one thing that hasn't changed that needed to change.
After seeing a pattern, I finally figured it out DAH!!  I can believe how stupid I have been.  
We did our own scientific study-we used condoms for a week.  Then one day did not.  Itchy feet, swollen eyes and really, really triggering for 3 days.  It is no wonder I have felt so bad over the last year.  I am actually afraid to try it again without the condom because of the reaction!  
On the up side, I have been more stable in the past 5 days than I have since this whole thing started. I also don't plan on having any more children!
I thought last week it was the fall weather making me so sick...while it may have played a role in my triggering, I think the majority of it was from my scientific study.  
Glad to figure this out, I'm happy and disappointed at the same time,
because I am mourning once again the loss of something else this stupid disease has taken from me.
Sorry, if I grossed anyone out, just wanted to share, just in case someone else has the same issue without realizing it.  Gives everyone something to think about.

I have heard of this before from my former allergist.  It can cause fertility problems for some people and make getting pregnant difficult.

Wondering if pre-medicating with extra antihistamines would help.

Oh poor us !!! (that includes our spouses too) I wonder if any men have reactions to us ???  
I couldn't help but laugh at some of the comments . I was so embarassed when I first brought it up on here. I discussed it with Lisa; and our "viagra" is an extra H1 about half an hour before. I thought I was going to have a stroke/aneurysm at one crucial moment. NOT sexy!  
So here's my question; is it a different trigger in certain cases ? IE: my husband's semen, OR the act itself ? I think I'm going to  buy some condoms & experiment a bit. OMG- can you imagine what the cashier gonna think of a 50 year old woman buying condoms ??? I could let Hubby get em- they might thing he's got a young chick on the side ...
Seriously, this felt good to share Pam- cuz it is a sensitive subject & such an important aspect in a relationship.

Pam;
Colored & textured?

You girls are hilarious!!!!  The crying happens to me too - no stopping it.  Thought I was the only one.

from the male perspective, likewise i think there is some sensitivity to the other sex. so many variables involved though difficult to pin point it specifically to this as the reaction isnt particularly severe. If my partner has been drinking wine and then kissing her that could likewise be the problem. How do you all do with kissing your partners when they have been drinking? Being a man i also have to contend with kissing lipstick, unsure if this is a trigger, but i'm guessing if one has MCAS so you probably have to be careful wearing it.
