Patient's question:
During sex with my girlfriend, I can't penetrate her cervix. She says she doesn't feel anything. My penis is 15 cm long when erect—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, so your condition is normal. As for the frequency of sexual life, it varies depending on different regions, climates, cultural backgrounds, and individual age, health status, and psychological interest.Guidance: Based on your condition, it is necessary to moderate sexual life, avoid excessive indulgence, and not have sex after fatigue. Consume more foods that have the effect of tonifying the kidneys and consolidating essence, such as walnuts, chestnuts, soft-shell turtle, pigeon eggs, and pig kidneys. If both parties do not feel tired and feel energetic, have the strength to work, do not affect sleep, and feel very comfortable physically and mentally, with abundant vitality that does not affect the next day's life and work, then it is considered normal. If the next day you feel physically weak, mentally sluggish, fatigued and sleepy, short of breath, dizzy, with aching waist and legs, decreased appetite, and it affects your life and work, then it is excessive and you need to self-regulate. For people aged 20-30, sexual activity is in a peak period, and it is recommended to have about 3 times per week.
