This is in response to an earlier post by someone asking if a person can be allergic to sex. You might consider this: Some people have a problem with prostaglandins. I have been diagnosed with Systemic Mast Cell Disease and one of the things that was occurring was reactions after sex…not always and to varying degrees. Turns out it was the prostaglandins that were triggering the reactions. (Go to NORD website and look up the disease if you want more info.) Every human produces prostaglandins but because I had an underlying disease my body viewed an increase of prostaglandins in my body as an allergen at times. I hope this helps you find an answer.
