Sex Q & A: "How long will it take normally until a man ejaculate?"

Nle, Malaysia:

Dear Doctor,

I just wonder how long normally a sexual intercourse will last from the moment of inserting the penis into the vagina until the man come? Roughly how many stroke it take before a man come?

Dearest Nle,

According to DR Master & DR Johnson , USA, normally ejaculation will happen 4 minutes after intermission in male (2 to 5 minutes). About how many strokes depends on the class you played, are you in the class of Pete Samprass or rather slow as Agassi. :)
