Question
Why do I find it impossible to reach my girlfriend’s cervix during intercourse? Is my erection length of about 15 centimeters too short? Also, is it normal for us to have sexual intercourse during our erections?
Answer
According to your description, your erection length is normal, and there is no need to worry excessively. The frequency of sexual activity varies due to personal age, health conditions, and psychological factors. It is recommended that you moderate your sexual activity and avoid overindulgence. Additionally, back pain may be caused by overuse, so it is advisable to rest more and consume some kidney-nourishing and essence-preserving foods such as walnuts, chestnuts, and softshell turtles to help your body recover.
