Could I Be Allergic to Sex?
(33M) For the past 17 years of being sexually active, I've occasionally experienced an unusual reaction that lasts from the moment after intimacy up to a full day later. I often find myself unusually fatigued, with a heavy sensation in my head, but the most troubling symptom is a burning sensation in my eyes. There are instances where I don’t notice these effects until the following afternoon, at which point I’ll recall, 'Right, I had sex last night; that explains the burning in my eyes.' This reaction has occurred with various partners, regardless of whether condoms were used. What’s particularly perplexing is that it doesn’t happen every time; it’s quite sporadic. Despite my attempts with antihistamines, such as both eye drops and oral medications, I haven’t found any relief. Fortunately, these occurrences have diminished lately, yet my curiosity about their cause remains strong, and unfortunately, no medical professional I’ve consulted has been able to explain it thoroughly. If anyone has insights or similar experiences, I would greatly appreciate your thoughts! Thank you in advance.

It sounds like you’re experiencing some concerning symptoms that are related to intimacy, and it's understandable that you're seeking clarity and possible solutions. Your description points toward a possible allergic reaction, though several other factors could be at play, given the variability and sporadic nature of your symptoms.
Understanding Your Symptoms
Your symptoms, particularly the burning sensation in your eyes and fatigue after sex, could indicate a few possibilities:
- Allergic Reaction: This could be to bodily fluids or certain lubricants, though you noted that this occurs with multiple partners and condom use.
- Post-Orgasmic Illness Syndrome (POIS): A rare condition where individuals experience flu-like symptoms, including fatigue and headaches, after ejaculation.
- Environmental Factors: If your partners use perfumes, lotions, or other products, these could also be triggers.
Next Steps
To address your concerns effectively, consider the following prioritized actions:
-
Symptom Diary: Keep a detailed record of when these symptoms occur, including the specific circumstances (partner, products used, etc.). Note any variations or patterns; this may help identify triggers.
-
Avoid Common Irritants: Pay attention to products that you or your partner use, such as soaps, lotions, or other personal care items. Try to minimize exposure to these on days when you anticipate intimacy.
-
Consult an Allergist or Immunologist: Since OTC antihistamines have not helped, seeking specialized evaluation may provide deeper insights. An allergy test may clarify if there are specific allergens involved.
-
Consider Lifestyle Adjustments: If you experience significant fatigue, ensure you're well-rested, hydrated, and managing stress, as these can influence your overall health and reaction to stimuli.
-
Monitor for Changes: As you’ve noted that your reactions have diminished, it’s worth continuing to observe this trend. If you notice any return or worsening of symptoms, revisit the idea of seeking professional advice.
Final Note
Your well-being is important, and while these experiences can be frustrating, many individuals have varying sensitivities that can sometimes change over time. Keep tracking your symptoms and stay open to discussing this with healthcare professionals who can help guide you toward understanding and managing your reactions better. If you have any more questions or need further clarity, feel free to ask!

Differentiating Between Histamine Reaction and Cellulitis
Subject: Male Height: 5’4” Status: Non-smoker Current Medications: None On the 15th, I experienced a bee sting. Although it caused some pain and a minor swelling, I initially had no severe reaction. However, after two days, a significant red patch emerged on my skin, accompanied by intense itching. I attempted to relieve the discomfort with calamine lotion and hydrocortisone cream, but neither provided any relief. This morning, I visited a minute clinic where the physician diagnosed me with cellulitis. I was prescribed a ten-day regimen of Cephalexin and a topical anti-itch medication, Triamcinolone, but the itching persists. I am skeptical about the cellulitis diagnosis since the itching is still quite severe. I haven’t experienced any fever or flu-like symptoms, and the redness has begun to fade since this morning. Would it be advisable to also take Benadryl?
Concern Over Dad's Bug Bite Reaction
Recently, my father, who is 63, scratched a bug bite on his leg, and I’ve noticed that the area has become swollen, inflamed, and painful. This incident occurred during nighttime, and he isn’t certain if the bite was from a tick. I’m wondering if the redness resembles the symptoms associated with Lyme disease or if it could indicate something that requires medical attention.
Identifying the Cause: Athlete's Foot or Allergic Reaction?
Age: 35, Male Ethnicity: Asian Residence: Bay Area Weight: 125 lbs For the past month, I've been experiencing an issue. Initially, I noticed tiny red spots that were quite itchy. I tried using a topical cream over several weeks, but instead of improving, the lesions expanded and appeared even more unusual. The treatment didn’t seem effective. Could this be a case of hives, as I suffer from them annually, or is it a fungal infection?
Concern About Possible Cold Sore
Greetings, I'm a 19-year-old female experiencing some anxiety over what seems to be a cold sore. Today, I discovered a tiny group of white bumps near the edge of my upper lip. They are accompanied by a tingling or numb sensation, making it difficult for me to determine whether this is simply due to dry lips or indeed an indication of a cold sore. If this indeed points to a cold sore, what steps should I take? I consider myself quite young and have never engaged in sexual activity; I’ve only kissed two individuals back in eighth grade. I'm perplexed about how I could be facing this issue now.
Identifying a Skin Condition: Eczema or Fungal Infection?
I’m a 20-year-old female, weighing 112 pounds and standing at 5 feet 4 inches, residing in California. I have a long history of dealing with eczema, but the current flare-up appears different from what I usually experience. The topical steroids prescribed for eczema have not been effective this time around. Although I have been applying clotrimazole cream, its results have been partial; I suspect it lacks the required potency. I previously attempted to use terbinafine but discovered that I have a severe allergy to it, preventing me from using that treatment. Does my condition appear to be fungal or is it still eczema? If it is indeed a fungal issue, I would appreciate recommendations for alternative treatments that could aid in my recovery.
