Can you be allergic to your partner’s cum?

Not all cum makes us feel the same when it’s inside us. As it turns out, some cum can leave us feeling damn itchy. Take it from this woman who posted in The Pleasurey asking about her cum-undrum.

Does anybody else find that after having sex and partner cumming inside that you’re extremely itchy afterwards, like everywhere? It doesn’t matter if it’s a 2 minute or a 30 minute session. I’ve never had this issue with any other guy, so I’m like oh shit am I allergic to him?

While rare, there is actually such a thing as a sperm allergy, formally called seminal plasma hypersensitivity. According to the Mayo Clinic, signs of a semen allergy include swelling, redness, and burning. Aka itchy as fuck! The good news is that if you’re trying to get pregnant, semen allergy isn’t considered a cause of infertility. But the bad news is, it may make you not want to have sex with your partner in order just to avoid a bad time.

The other thing that could be going on is some kind of imbalance where the sperm is changing your natural pH. A normal vaginal pH level is between 3.8 and 4.5, which is moderately acidic. Sperm, on the other hand, is naturally alkaline. During intercourse, the pH level of the vagina temporarily rises to make the environment more alkaline and help protect the little guys swimming up. But it can also create an environment ripe for the growth of bad bacteria. And that’s why some women report getting yeast infections after sex. But according to one OBGYN doctor, it’s far more likely that you have something called bacterial vaginosis (BV).

BV is a result of bad bacteria overgrowing the good and it can cause painful itchiness, but also a burning sensation when you pee, white/grey discharge, and perhaps even a fishy odor. So, if you’re having sex with the same partner and constantly finding yourself burning and itching, it could be that you’re literally reawakening this bad bacteria every time you’re having sex.

The good news is that for both BV and semen allergy there are treatments you can do to eliminate or at least control the problem.

Far more complicated, though, is this scenario: that your bad reaction to his cum is just your body’s way of telling you he’s just not right.

As one woman shared of her reaction to former lovers’ cum,

I’ve experienced that a few times in my life.. it was usually when it wasn’t a full body yes from me. It used to happen with both my ex husbands. I think subconsciously I was rejecting them after they’d cheated on me quite a few times. I don’t ever experience that with my current partner. 💛

Whether or not he’s right for you, to find out why you’re burning, consult your doctor.
