Hello, I have a question about my sex like I am a healthy 19 year old male, my girlfriend is 18 and also healthy. About a month ago we started having sex, there were no problems up until a few days ago. We were having intercourse and the position we wanted to do next required her to put her leg behind her leg, after that we started again and within a few minutes of having sex she said she felt like she needed to urinate. We changed positions numerous times and she still had the same problem. So we decided to call it quits for the night so we could get up in the morning and go to planned parenthood, we went there thinking it would be something not so serious like a Urinary tract infection, when we got the results back they came back negative and the doctor said of all things was that she didn't quite know and maybe it was the size of my penis. I still to this day question that so now I'm here asking this question going to get a better answer, could you please help me. It would be much obliged. Thank you . Sincerely Malik.
