i get nauseated about 15 mins after any type of sex. What is going on?

My husband and i have been married for 3 years now, and without fail, every time we have intercourse, be it oral or vaginal, i get extremely nauseated about 15 to 20 mins after we are done. it will last well into the next day. There is not a very likely chance that pregnancy is involved in any way because my husband had a very successful vasectomy 2 years ago and i am on birth control besides that. a doctor suggested that i may be allergic to his ejaculations, but that really does not make sense to me since i get sick no matter what kind of sex we have. i want to be free to make love to my wonderful hubby with out knowing i am going to be extremely sick for doing it. and it makes him feel bad and not want to have sex with me cause he does not want to make me sick. whatever help or advice you could offer would be wonderful. thank you for your time.

Hi Anonymous,
So glad this seems to have been resolved for you.
Good thing you asked your doctor about it. Good luck, and hope the situation continues to improve.

I looked into the things everyone posted. My doctor told me he suspected it was a combination of my cervix being hit and a really bad allergy to semen. He prescribed me some medication to take directly after sex that has been making a drastic improvement on the nausea. both my husband and I are much happier now. Thank you every one for all your advice.

Hi Anonymous,
Thanks for your brave posting. Did you doctor say anything about what can be done about a possible semen allergy? I recently wrote an article about Dyspareunia that is not exactly your condition but also can be related to semen allergy and what you're experiencing--it may be worth checking into: https://www.empowher.com/painful-sexual-intercourse/content/dyspareunia-painful-intercourse-advocacy-sheet
I would go back to your doctor, or try and talk with a friend's doctor to see if they can help your condition and help make sex with your husband more enjoyable. Good luck and please come back and update us on your progress.

Thank you for your questions anonymous,

I have to admit that this is the first time that I have heard about this issue but after doing a search for an answer for you, there appears to be a great deal of people who also share in your misery.

The research I found is that other people have found that the penis hitting the cervix can cause nausea although you say that even oral sex causes this for you. Does this occur everytime you have any sexual relations? Is sperm involved everytime you are ill? If he performs oral sex only on you, does that make you ill also?

I will certainly try and help answer your question, but be as specific as possible about what exactly causes the nausea.

I have a couple of questions for you. I have heard of this before.

Do you get very overheated when you have sex? I mean, super hot and sweaty? Do you get very overheated with other activities and become nauseated?

My other question is, have you ever been a fainter? One of those people who gets woozy at the site of certain things or when you are shocked or anything like that?

The two things I am thinking of is first, if you get really overheated it may be that you are experiencing a low blood pressure. When you get hot and your heart rate goes up the response by your body is to relax your blood vessels to let the heat escape more easily. This lowers your blood pressure and can cause nausea.

The other thing is a vasovagal response. Your vagus nerve innervates most of your trunk. If you have anal sex, it can stimulate the vagus nerve. But also, people who faint with a scare or at the sight of blood have a vasovagal response that make them faint. I wonder if somehow during sex your vagus nerve is being stimulated? This sort of explains it: https://www.empowher.com/media/reference/fainting. You don't have to completely pass out for it to be a vasovagal thing.

I don't know if this helps, but those are the first things I thought of.
