How can i ejaculate more while having sex to have this baby

Patient: Ok so me and my girlfriend want to have a baby but I can’t seem to ejaculate when we have sex.. what could be the problem

Symptoms: None

Doctor: Hello,If you have been ejaculating even 2ml of semen , it i enough for her to get pregnant if the sperms are motile. I feel you should spend more time on foreplay to help you get over premature ejaculation.regards
