Vaginal yeast infection, also called vulvovaginal candidiasis occurs when the healthy yeast that lives in your vagina grows out of control and leads to an infection. It is not a sexually transmitted infection, however, develops after vaginal intercourse  .
Yeast infections are extremely uncomfortable and irritating and sexual activities increases the risk of infection developing, by introducing new bacteria to the vagina.
Commonly found in women, yeast infections are not serious and are treatable with over-the-counter medications. It is stated that almost all women will develop a yeast infection at some point in their life   .
Causes Of Yeast Infections After Sex
The overgrowth of Candida fungus, a microscopic fungus growing in the vaginal environment is the cause of yeast infection after sex. The fungus is a normal part of the bacterial ecosystem in your vagina.
During intercourse, the bacteria from your partner's finger or penis will enter your vaginal ecosystem - resulting in the development of yeast infection. Bacteria can be introduced via sex toys too  .
This entrance of new bacteria causes a disruption which triggers a vaginal yeast infection.
Vaginal yeast infection can also develop when involved in intercourse with an individual who has a penile yeast infection. Chances of one contracting vaginal yeast infection after sex may be due to the factor that your partner will also be having a yeast infection. In the same line, you can pass the infection to your partner if you have sex after developing yeast infection  .
Oral sex increases the risk of vaginal yeast infections, studies assert. This is because while performing oral sex, Candida and bacteria from your partner's mouth, tongue, and gums can enter to your vulva.

Treatment For Yeast Infection After Sex
If you suspect that you have an infection, consult a doctor rather than self-diagnosing. Although you can easily understand if you have a yeast infection or not and get it treated with over-the-counter creams such as miconazole or butoconazole - going to a doctor can be beneficial because he or she can rule out the possibilities of severe infections  .
The most commonly prescribed medication for yeast infection is antifungal medications which can be brought without a prescription, as mentioned before.
The medicines are available in the form of creams, pills, ointments and suppositories  .
Note: If you are getting over-the-counter medication, ask the pharmacist about the dosage and possible side effects.
Prevention Of Yeast Infection After Sex
The first and foremost measure involved in preventing yeast infection after sex is by a condom. Having protected sex can help keep the infection from developing  .
The other method is the use of a dental dam, a latex or polyurethane sheet that can be used during vaginal oral sex or anal sex. It is also called an outside condom as it is placed on the outside.
These can help in minimising the spread of infection-causing bacteria during sexual activity.
Some of the other ways through which you can minimise the risk of developing vaginal yeast infection are as follows  :
- Reduce your consumption of carbohydrate- and sugar-rich foods.
- Use breathable cotton undergarments.
- Avoid using perfumed soaps or other hygiene products on your genitals.
- Consume more of Greek yoghurt as it contains good bacteria that can help fight yeast infection.
- Avoid douching.
