Does new sperm "cancel" out the sperm that was ejaculated the day before?

Ok, this may sound like a weird or dumb question, but I honestly don't know the answer. This is an example of what I am trying to explain. Say my boyfriend "came" in me Tuesday....Then on Thursday we have sex again and he comes in me again.....does the sperm on Thursday cancel out the sperm left on Tuesday, or does the "come" on Thrusday just add to the amount of sperm from Tuesday until the sperm from Tuesday dies? Sorry if it is confusing!

Answers:
Oh my God !!!! No ....And by the way why would you want to know and how did this thought come to mind ? I'm not trying to be rude I really want to know how you thought of this.
