How deep we have inserted the dick at the time of ejaculation? -
As deep as you can. involuntary muscle reactions make sure you are at your max. depth.
It hardly matters.
At the point of ejaculation the bodies instant reaction is to drive it home as much as possible, this is why the -withdrawal- method of contreception is almost impossible to do because, they say -at the point of ejaculation, withdraw-.... Yeah right... there isn-t a team of wild horses that would be able to stop my man thrusting at the point of ejaculation!!!
