Dear Doctor, Greetings of the day!!! I am a 31 years male. My problem is fast ejaculation. Initially,I mean during the first time sex, it was like during foreplay when my partner do the hand job, ejaculation happened very fast. But later somehow I managed that, but now the problem is when my thing goes inside to my partner all of a sudden ejaculation happens, except partner on top position. Doctor please advice me. Thank you.
