What is the ideal time for intercourse ?

Hi,

Can anyone tell me what is the ideal time for an intercourse?
I am afraid as I usually c*m in two hour, so I am worried like is two hours of actual penetration is less?
I dont want ot lose my gal as I am confused abt the ideal time duration of...

actual penetration.

There is no ideal time, its varies a lot from guy to guy. If your worried about your lady leaving you because of how long you last, then you need to find yourself a new lady because you should never need to worry about that kind of stuff when your in a serious relationship with someone.
