What kind of pain do you have?
Does it feel like its inside of you or is it at the surface or at the opening?
Do you have any itching or burning?
What kind of discharge do you have?
The sex act alone shouldn’t have made you be in pain like this. Usually after a couple of days the soreness goes away. Did you use protection? If not you could have gotten an STD. STD’s can cause pain, usually burning, itching, or unusual or smelly discharge. Or you could have gotten a urinary tract infection. UTI’s can happen to anyone. During sex bacteria could have gotten in the wrong place. Pregnancy doesn’t seem likely…at least you wouldn’t feel the symptoms yet.
Is there a doctor you could see? I suggest you should see one anyway. Us as women need to start regular gyno visits once we start having sex. For birth control, pregnancy, and yearly health exams.
Hope I didn’t type too much. I just remember my 1st times. No one told me anything about my body. So I was confused a lot.
