I am female Post Menopausal and have been sex abstinence for several years. I have now met a new partner and we had intercourse, we used lubricant and condom. It was a bit painful but not too bad. Two days late I had UTI symptoms (urge to urinate, pink urine, shivering) for few hours but all disappeared few hours later. The urine test showed no bacteria. I am 63 and never had UTI so I am almost sure it is due to being sexually active after abstinence for long. I wonder what to do to avoid this problem in future. How soon can I resume sexual activity. What to do to make the sexual experience less painful.
