Can having too much sex cause a yeast infection? i was having sex 2 to 3 times a day (young and a newlywed). i did pee after to prevent uti.

No - this is rare.: It is rare to develop a yeast infection from sex. What is not rare is to develop irritation that feels like a yeast infection during frequent sex. See this for more information http://www.womenshealth.gov/publications/our-publications/fact-sheet/vaginal-yeast-infections.html

No.: Frequent sexual intercourse does not cause yeast infection.
