When I have sex with my boyfriend, his penis stings afterwards but I have no symptoms? Is it possible that it's the acidity?

Good evening ma'am,

Yes, it could be acidity or irritation.

I recommend that you try using a personal lubricant if not already used. If your partner is not circumcised, he or she should also wash the glans after each sexual encounter (soap and water), as the mere presence of yeast normally found in the healthy vagina can be enough to cause itching.

Happy evening,
