But how is the nanorobot getting to the situation? From the guy or do you have to put it up the vagina as some kind of anti-birth-control?
Is it a good idea at all to help slow/problematic sperm to "reach the goal"?
What if it comes along with the sperm and you do an anal creampie?
This is a bit scary, yeah, but I can't wait until the nano-technology reaches the point when the robots can clean your veins for example..
