<s>[INST] Good Morning... i have a question... i am planning for a family what i have realized that while having intercource i donot eject semen everytime. it ha shappened to me couple of times.. need to know whether i should consult a doctor or is it normal??? [/INST] Hello, In some men this problem is seen. Try changing position. Spend time in foreplay and continue pushing (remaining still inside the vagina may cause lack of stimulation and ejaculation problem). Try Keel exercise.  If still the problem persists, please consult doctor to find out the cause. The problem may lie in the prostate gland, blood sugar or in the spine or nerve. In few men, the problem can persist despite all treatment.  In that case, you can try self-insemination (collecting semen at home and inserting it inside the vagina) It works. Some of my patients conceived after this self-insemination.  Hope I have answered your query. Let me know if I can assist you further. Take care  </s>
