Patient's question:
During sex with my girlfriend, I can't penetrate her cervix. She says she doesn't feel anything. When my penis is erect, it's 15 cm long—is that too short? Also, it's often hard when I sleep with her. What's going on? Last night, I had sex three times, and today I'm feeling a bit sore in my lower back. What should I eat to feel better? Thank you, March 12, 2010Doctor's answer:
Analysis of the condition: Hello! Sexual life is happy as long as both parties are satisfied. There is no need to deliberately pursue the size of the reproductive organs. Therefore, your condition is normal. As for the frequency of sexual life, it varies depending on different regions, climates, cultural backgrounds, as well as individual age, health status, and psychological interest.Guidance: Based on your condition, it is necessary to moderate sexual life, avoid overindulgence, and not have sex after fatigue. Consume more foods that have the effect of tonifying the kidneys and consolidating essence, such as walnuts, chestnuts, softshell turtle, pigeon eggs, and pig kidneys. If both parties do not feel tired but instead feel energetic, have the strength to work, do not affect sleep, and feel very pleasant both physically and mentally, with no impact on the next day's life and work, then it is considered normal. If the next day you feel physically weak, mentally lethargic, tired and sleepy, short of breath, dizzy, with aching waist and legs, decreased appetite, and an impact on life and work, then it is excessive and you need to self-regulate. For people aged 20-30, sexual activity is at its peak, and it is recommended to have about 3 times per week.
