I had sex for the first time 5-6 days ago, but I still feel pain when I urinate, frequent urination and sometimes a little blood in my urine even though the first time sex was very gentle. Doctor, can you tell me if it's okay to have blood when urinating, painful urination, and frequent urination after sex?

Hello doctor, for almost a week now I often have pain when urinating (when urinating), please tell me what disease i have? Thank you doctor!
