This is a really good question. A lot of women tend to get yeast infections after sexual intercourse, and they assume it’s something about the intercourse itself that’s causing the problem. That’s not generally the case. Please look at why women tend to get yeast infections more often here.
First, it’s important to remember that the vaginal environment is very delicate. It exists at a certain pH level and hormonal fluctuations of any sort can tip the balance in the favor of yeast growth. Women who have not had intercourse for an extended period of time may find that intercourse, or frequent intercourse, causes an issue. The type of condom you use, especially if it is latex or is coated in some sort of lubricant, can also cause irritation. This is because you’re suddenly altering the vaginal environment. Most women simply need to take a break and treat the infection and don’t have much issue when they resume normal sexual activity.
Another factor to consider is whether or not your partner has a yeast infection already. While yeast infections aren’t sexually transmitted diseases in the truest sense, they can be passed from person to person via physical contact. If your female partner has a vaginal infection, or if your male partner has jock itch – whether he or she knows it or not – you can catch it.
The most common causes of yeast infections aren’t really related to sex, but to the current state of your overall immune system, hormonal fluctuations, and medication use. If you have a recurring infection or one that seems to not want to go away, make sure you visit your doctor or naturopath. You may have a more serious underlying condition that needs to be addressed.
