How long does it take for average of man to ejaculate?

Difficult question: Ejaculation time varies man to man and event to event. Depends on energy level, stimulation pace, time between events, drugs/meds on board, fatigue, health, etc. Broad range is about 2-15 minutes, with tighter average being 4-6 minutes. Best to do your own research...be safe!

Here are some ...: Most men ejaculate within 3-10 minutes after vaginal penetration. Today, in fact, the ongoing acceptable definition for premature ejaculation is ejaculation within 1 minute after penetration.

No telling: Some are quick, while others take longer. 5-10 would be my guess, but that's far from universal.
