Stupid question

Ok I know this is stupid but before I start...

No I'm not on birthcontrol. And if I do end up pregnant both of us are fine with it...

But my question is... that he sometimes comes in me when we have sex but majority of those times he will masturbate and make hisself come maybe minutes or hours before we do have sex.

Is that diluting the sperm count so when he comes in me its less of a chance of getting pregnant???
