Dear service user, Thank you for writing to healthcaremagic. I have gone through your question and understand your concerns regarding delayed ejaculation (You say sperm do not come out soon) during sexual intercourse with partner. When you masturbate, you can ejaculate easily. This seems partner specific orgasmic dysfunction. I I recommand you to see psychiatrist well versed with psychosexual therapies. Behaviour therapy like sensate focus exercise and sensual intercourse are proven successful for similar problems. He will definitely assist you. Your problem has nothing to do with birth of child so avoid unnecessary worries regarding that. Be relaxed. I hope this will help you.
