I wouldn't have thought so but you could try stopping them for a few days, or you could change the PH of your urine to alkaline. You can do this with citrate salts (I buy URAL sachets from the pharmacy) or with one of the many home remedies you can find by doing an Internet search. One of those is: Take 1/4 teaspoon citric acid + 1/4 teaspoon of baking soda for two weeks.

I am not a doctor but I do think your problem is most likely an irritation caused by your increased sexual activity but as you still sound anxious, then maybe you should see your doctor if only to ease your concern.
