Hi, I have gone through your query and here is the possible explanation for your symptoms. During an intercourse, especially for the first time, there is pressure on the urethra and this can cause a condition called Honeymoon Cystitis . There is an intense desire to pass urine, called strangury . There is often no evidence of infection and the condition is self-subsiding in 2-3 days. This is more when the uterus is retroverted, since the urethra is very much exposed in this case. Flavoxate gives relief from the strangury, while urinary alkalinizers are used to limit infection. Antibiotics are rarely needed. Take plenty of liquids and see your health care provider for further management. Abstain until you are healed well. Take care.
