question: I had unprotected sex with an ex girlfriend from the past. We just recently reconnected again and she said she hasn t been with anyone in 2 years and also recently had a complete check up done with flying colours. We tried having sex multiple times unfortunately I kept having to stop due too discomfort. For seven days after we did nothing cause it felt like the head of my penis was being pinched constantly. We tried again and the same problem occurred. It s now 10 days later and I m still experiencing the same discomfort. What could cause this? I m 40 years old and never had anything like this happen before even when I had very rough long and regular sex.
