What Causes Frequent Urination After An Intercourse?

Hi, I am 29 years old female and sexually active. Since last night after intercourse i have noticed that I am peeing a lot and I get a ticklish feeling while peeing. And then after peeing urge to pee more and its very less. The color of the pee is light yellow. I drink tea 3 cups daily and maybe 1 glass of water and orange juice. Please advice.
